Requirements
------------
You must be using a kernel with Ted Ts'o's new TTY subsystem. My
driver has been run on 1.1.23, 1.1.41, 1.1.45, and 1.1.64 (those
are the releases that I developed with). I'm not sure of the
release number where the TTY subsystem was revamped. :-(
A good lithmus test--I think--would be to check for the n_tty.c,
tty_io.c, tty_ioctl.c files in /usr/src/linux/drivers/char. If
these files exist, I would think that you have the new TTY subsystem.
Distribution Files
------------------
This distribution contains these file:
pcxe.c DigiBoard PC/Xe and PC/Xi driver
pcxx.h Driver data structures and defines
fep.h FEP/OS data structures and defines
digi.h Include files needed by the driver
digi_fep.h DigiBoard's onboard FEP/OS
digi_bios.h DigiBoard's onboard BIOS
pcxxconfig.h Configuration file generated by digisetup
(DO NOT EDIT BY HAND!!!)
ditty.c ditty program to set Digi-specific port options
digisetup GUI configuration program to add or remove boards
dialog program needed for digisetup. Place in /bin directory.
All these files should be in the /usr/src/linux/drivers/char directory.
You can move ditty.c and copy the needed include files to a separate
directory if you wish. To make ditty, simple type 'make ditty'.
Also, you can move the 'digisetup' program to a 'bin' directory if you
wish. It is not dependent on it's current directory.
Changes
-------
The following changes must be made to files in the Linux kernel distribution
in order for the driver to compile. The changes are few and simple:
1. In the file /usr/src/linux/drivers/char/tty_io.c, add this
line below the "kmem_start = pty_init(kmem_start);" line:
kmem_start = pcxe_init(kmem_start);
2. In the file /usr/include/linux/tty.h, add this line below
the "extern long tty_init(long);" line:
extern long pcxe_init(long);
Also, add this line below the "extern int pty_open(..." line:
extern int pcxe_open(struct tty_struct *tty, struct file *filp);
3. In the file /usr/include/linux/interrupt.h, add this line
under the "TQUEUE_BH," line:
DIGI_BH,
4. In the file /usr/src/linux/drivers/char/Makefile, add the
word "pcxe.o" to the "OBJS=" line and add the word "pcxe.c"
to the "SRCS=" line.
5. Now you are set. The pcxxconfig.h file in the drivers/char
directory contains the information on how many boards are
configured and where their I/O addresses are, etc. Do not
edit this file by hand! This file is parsed and generated
by the 'digisetup' configuration utility. It is then used
during compilation so that when the machine boots up, it
can find the boards at their respective memories and I/O
ports.
Run the 'digisetup' configuration utility to add your board(s).
Be sure you choose memory addresses and I/O ports that do
not conflict with other devices. The device files will be
created for you, after asking your permission. Non-modem
devices are /dev/ttyd* and modem-control devices are /dev/ttyD*.
Their major numbers are 30 and 31 respectively. If this
conflicts with your setup (I'm pretty sure it won't), feel
free to change the DIGIMAJOR and DIGICUMAJOR variables to change
the major numbers of the devices.
After you have run the 'digisetup' utility, rebuild the kernel.
6. A word about /etc/inittab and getty. Each card has 16 devices
assigned to it--even if it's a 2-port card. Thus, a PC/2e
will have tty[dD]1 - tty[dD]16 allocated to it, even though
only tty[dD]1 - tty[dD]2 are available for opening. Attempts
to open tty[dD]3 on a PC/2e, for example, will result in a
"No such device" or (ENODEV) error.
Board 1 will have tty[dD]1 - tty[dD]16, board 2 will own
tty[dD]17 - tty[dD]32, and so on, up to seven boards for
a total of 112 ports. Why seven boards? There are only
seven available I/O addresses on the cards. :-)
Here is a typical entry I have in my /etc/inittab for non-
modem control devices:
e2:45:respawn:/sbin/agetty -L 110 ttyd18
ttyd18 is the 2nd port on the 2nd board. The '-L' option
must be specified for non-modem control devices to force
CLOCAL. Otherwise it will just hang after typing your
login name, waiting for carrier detect. The 110 baud
maps to 115K baud when fastbaud is turned on. Fastbaud
should be turned on in the /etc/rc.d/rc.local file with
the following command:
ditty fastbaud ttyd18
This ensures that fastbaud is enabled on ttyd18 by the time
the getty is spawned. :-) Fastbaud is a 'sticky' option (i.e.
the port doesn't have to remain open for the setting to stick).
The ditty command should be used in the /etc/rc.d/rc.local
much in the same way the setserial command is used to configure
the com ports. One more example, "ditty altpin ttyd18" can be
used to enable the altpin feature without running 'digisetup'
and recompiling the kernel.
If you want someone to be able to call into your machine on
board 4, port 1, with a modem, try this line:
d1:45:respawn:/sbin/agetty 38400 ttyD65

the kernel to use the driver, make a backup boot disk if you
don't already have one...and backup your data!
Beta Testing
------------
I _want_ to hear if you were successful in running 7 boards simultaneously,
or if you have any benchmark issues. I have not tried PPP or SLIP yet,
so it may not work. I may have left out a few line discipline hooks, but
I don't think so. I would like to hear how PPP worked for you.
Also, feel free to email me on how you are using this driver...which
products, how many, and where did you purchase the boards? In general,
please gimme some feedback! ;-)

A much more important factor in the social movement than those already mentioned was the ever-increasing influence of women. This probably stood at the lowest point to which it has ever fallen, during the classic age of Greek life and thought. In the history of Thucydides, so far as it forms a connected series of events, four times only during a period of nearly seventy years does a woman cross the scene. In each instance her apparition only lasts for a moment. In three of the four instances she is a queen or a princess, and belongs either to the half-barbarous kingdoms of northern Hellas or to wholly barbarous Thrace. In the one remaining instance208— that of the woman who helps some of the trapped Thebans to make their escape from Plataea—while her deed of mercy will live for ever, her name is for ever lost.319 But no sooner did philosophy abandon physics for ethics and religion than the importance of those subjects to women was perceived, first by Socrates, and after him by Xenophon and Plato. Women are said to have attended Plato’s lectures disguised as men. Women formed part of the circle which gathered round Epicurus in his suburban retreat. Others aspired not only to learn but to teach. Arêtê, the daughter of Aristippus, handed on the Cyrenaic doctrine to her son, the younger Aristippus. Hipparchia, the wife of Crates the Cynic, earned a place among the representatives of his school. But all these were exceptions; some of them belonged to the class of Hetaerae; and philosophy, although it might address itself to them, remained unaffected by their influence. The case was widely different in Rome, where women were far more highly honoured than in Greece;320 and even if the prominent part assigned to them in the legendary history of the city be a proof, among others, of its untrustworthiness, still that such stories should be thought worth inventing and preserving is an indirect proof of the extent to which feminine influence prevailed. With the loss of political liberty, their importance, as always happens at such a conjuncture, was considerably increased. Under a personal government there is far more scope for intrigue than where law is king; and as intriguers women are at least the209 equals of men. Moreover, they profited fully by the levelling tendencies of the age. One great service of the imperial jurisconsults was to remove some of the disabilities under which women formerly suffered. According to the old law, they were placed under male guardianship through their whole life, but this restraint was first reduced to a legal fiction by compelling the guardian to do what they wished, and at last it was entirely abolished. Their powers both of inheritance and bequest were extended; they frequently possessed immense wealth; and their wealth was sometimes expended for purposes of public munificence. Their social freedom seems to have been unlimited, and they formed combinations among themselves which probably served to increase their general influence.321 The old religions of Greece and Italy were essentially oracular. While inculcating the existence of supernatural beings, and prescribing the modes according to which such beings were to be worshipped, they paid most attention to the interpretation of the signs by which either future events in general, or the consequences of particular actions, were supposed to be divinely revealed. Of these intimations, some were given to the whole world, so that he who ran might read, others were reserved for certain favoured localities, and only communicated through the appointed ministers of the god. The Delphic oracle in particular enjoyed an enormous reputation both among Greeks and barbarians for guidance afforded under the latter conditions; and during a considerable period it may even be said to have directed the course of Hellenic civilisation. It was also under this form that supernatural religion suffered most injury from the great intellectual movement which followed the Persian wars. Men who had learned to study the constant sequences of Nature for themselves, and to shape their conduct according to fixed principles of prudence or of justice, either thought it irreverent to trouble the god about questions on which they were competent to form an opinion for themselves, or did not choose to place a well-considered scheme at the mercy of his possibly interested responses. That such a revolution occurred about the middle of the fifth century B.C., seems proved by the great change of tone in reference to this subject which one perceives on passing from Aeschylus to Sophocles. That anyone should question the veracity of an oracle is a supposition which never crosses the mind of the elder dramatist. A knowledge of augury counts among the greatest benefits222 conferred by Prometheus on mankind, and the Titan brings Zeus himself to terms by his acquaintance with the secrets of destiny. Sophocles, on the other hand, evidently has to deal with a sceptical generation, despising prophecies and needing to be warned of the fearful consequences brought about by neglecting their injunctions. The stranger had a pleasant, round face, with eyes that twinkled in spite of the creases around them that showed worry. No wonder he was worried, Sandy thought: having deserted the craft they had foiled in its attempt to get the gems, the man had returned from some short foray to discover his craft replaced by another. “Thanks,” Dick retorted, without smiling. When they reached him, in the dying glow of the flashlight Dick trained on a body lying in a heap, they identified the man who had been warned by his gypsy fortune teller to “look out for a hidden enemy.” He was lying at full length in the mould and leaves. "But that is sport," she answered carelessly. On the retirement of Townshend, Walpole reigned supreme and without a rival in the Cabinet. Henry Pelham was made Secretary at War; Compton Earl of Wilmington Privy Seal. He left foreign affairs chiefly to Stanhope, now Lord Harrington, and to the Duke of Newcastle, impressing on them by all means to avoid quarrels with foreign Powers, and maintain the blessings of peace. With all the faults of Walpole, this was the praise of his political system, which system, on the meeting of Parliament in the spring of 1731, was violently attacked by Wyndham and Pulteney, on the plea that we were making ruinous treaties, and sacrificing British interests, in order to benefit Hanover, the eternal millstone round the neck of England. Pulteney and Bolingbroke carried the same attack into the pages of The Craftsman, but they failed to move Walpole, or to shake his power. The English Government, instead of treating Wilkes with a dignified indifference, was weak enough to show how deeply it was touched by him, dismissed him from his commission of Colonel of the Buckinghamshire Militia, and treated Lord Temple as an abettor of his, by depriving him of the Lord-Lieutenancy of the same county, and striking his name from the list of Privy Councillors, giving the Lord-Lieutenancy to Dashwood, now Lord Le Despencer. "I tell you what I'll do," said the Deacon, after a little consideration. "I feel as if both Si and you kin stand a little more'n you had yesterday. I'll cook two to-day. We'll send a big cupful over to Capt. McGillicuddy. That'll leave us two for to-morrer. After that we'll have to trust to Providence." "Indeed you won't," said the Surgeon decisively. "You'll go straight home, and stay there until you are well. You won't be fit for duty for at least a month yet, if then. If you went out into camp now you would have a relapse, and be dead inside of a week. The country between here and Chattanooga is dotted with the graves of men who have been sent back to the front too soon." "Adone do wud that—though you sound more as if you wur in a black temper wud me than as if you pitied me." "Wot about this gal he's married?" "Don't come any further." "Davy, it 'ud be cruel of us to go and leave him." "Insolent priest!" interrupted De Boteler, "do you dare to justify what you have done? Now, by my faith, if you had with proper humility acknowledged your fault and sued for pardon—pardon you should have had. But now, you leave this castle instantly. I will teach you that De Boteler will yet be master of his own house, and his own vassals. And here I swear (and the baron of Sudley uttered an imprecation) that, for your meddling knavery, no priest or monk shall ever again abide here. If the varlets want to shrieve, they can go to the Abbey; and if they want to hear mass, a priest can come from Winchcombe. But never shall another of your meddling fraternity abide at Sudley while Roland de Boteler is its lord." "My lord," said Edith, in her defence, "this woman has sworn falsely. The medicine I gave was a sovereign remedy, if given as I ordered. Ten drops would have saved the child's life; but the contents of the phial destroyed it. The words I uttered were prayers for the life of the child. My children, and all who know me, can bear witness that I have a custom of asking His blessing upon all I take in hand. I raised my eyes towards heaven, and muttered words; but, my lord, they were words of prayer—and I looked up as I prayed, to the footstool of the Lord. But it is in vain to contend: the malice of the wicked will triumph, and Edith Holgrave, who even in thought never harmed one of God's creatures, must be sacrificed to cover the guilt, or hide the thoughtlessness of another." "Aye, Sir Treasurer, thou hast reason to sink thy head! Thy odious poll-tax has mingled vengeance—nay, blood—with the cry of the bond." HoME古一级毛片免费观看
