Well, I put my machine on line Oct 1987 and have been using only ph0
since then. I have had problems, but the fix disk solved the un-
explained machine lock-ups. The inode bug has bit me several times,
too, but hopefully the *next* fixdisk will solve that. I have had NO
problems traceable to pho hardware.
Many people have asked for phstat, my shell script that I use to control
uucico transfers, and any other info I can give them. Here it is ...

X phstat.c
X===================================
X
X PHSTAT is called with the device descriptor of the phone
Xdevice whose status is desired, ie:
X
Xphstat /ph0
X
Xwill return the status of phone line 0. The status is returned on
Xstandard output as a text string indicating the state as follows:
X
X VOICE-IDLE indicates line is idle in voice mode
X
X VOICE-ACTIVE indicates line is in voice mode with a
X conversation in progress.
X
X DATA indicates line is data mode.
X
XCurrently phstat will not detect the RINGING condition as such. I think
Xthis is returned as status VOICE-ACTIVE, but I'm not sure.
X
X PHSTAT will return via an exit(1) if it is called improperly,
Xand with an exit(0) otherwise.
X
X To compile phstat with shared libraries:
X
Xcc -c -ophstat phstat.c
Xld -o phstat phstat.o /lib/crt0s.o /lib/shlib.ifile
X
X I installed phstat in /usr/local/bin/phstat with user bin,
Xgroup bin and permissions 755.
X
X===================================
X uusites.poll
X===================================
X
X This file is the shell script I use to initiate the uucp
Xconnection to my feed site. There are two things you *HAVE* to
Xchange if you want to use this for yourself:
X
X Change variable SITE to be the name of the site you are calling.
X Change variable SITE1 to be the first 6 characters of SITE.
X
XI put this shell script in /usr/lib/uucp/uusites.poll with user uucp,
Xgroup mail, and permissions 755. I modified my crontab file to run this in
Xplace of the uudemon.hr script. It is set up so I can also run it as
Xan ordinary user for special occasions.
X
XMy system uses the standard ATT uucp (not HoneyDanBer), and I call my feed
Xsite to establish the connection. I also contact only one site. If you
Xwant to contact more than one site you will have to modify the script to
Xsuit your needs.
X
X Several important things I have learned in setting this up:
X
X1) All uucp activity is logged on a file /usr/spool/uucp/LOGFILE.
X The standard system setup manages this log file weekly so it
X doesn't overflow your disk. Keep an eye on this file regularly
X to see what's going on with your uucp connection. Many problems
X will first show up here.
X
X2) If a uucico fails for any reason, it leaves a status file (named
X STST<something> laying around in the /usr/spool/uucp directory.
X The presence of this file will prevent uucico from attempting a
X retry before some default time (usually 1 hour). The script
X removes all STST* files from the spool directory to allow a
X shorter retry period.
X
X3) Before you change the state of the phone line, you *must* save
X its current status. This is required to decide what to do after
X the uucico is completed. Remember that a successful uucp
X connection can run for hours! Cron (or you) may invoke this
X shell script *several times* during this time period. You
X don't want one of these redundant invocations to screw up
X a perfectly good phone connection. Uucico will properly
X handle multiple invocations of itself, but it doesn't know or
X care anything about the phone device. YOU must handle that!
X
X4) The trap statement is in there to prevent normal things (like
X logging out) from messing up a successful connection. It
X probably isn't needed if you only run the script from cron,
X but I like to be able to run it manually for debugging and
X other special occasions (like a power failure right before
X cron would normally run it!). The trap protects me from
X myself.
X
X5) The phtoggle program will properly check for all error
X conditions regarding the phone line. It won't try to control
X it if it is being used by someone else, and it takes care of
X all the lock files. Unfortunately, if it does fail for an error
X condition it doesn't seem to tell you in a way that can be
X detected in the shell script. It just leaves an error window
X laying around on the console. That's how I found out what
X situations my shell script wasn't handling properly.
X
X6) I now use a dummy poll file to detect whether or not the uucico
X transfer was successful. This is an empty file named so uucico
X thinks it is a queued up job waiting to be acted on. When it
X discovers the file is empty, it just skips it. This isn't done,
X however, until a complete connection has been successfully
X established. So, if you had a good connect, the poll file will
X disappear. If the connection failed (initially) the poll file
X will still be around. If the connection fails after it had
X been successfully established, the poll file will also disappear
X and the shell script will not retry. This was done at the request
X of my feed site, so they can effectively ignore me (by allowing
X my login, turning the line around, then killing the connection)
X if they have higher priority things to do and don't want my
X machine repeatedly beating the door down trying to get in.
X This shell script can be painfully persistent in trying to
X establish a good connection otherwise!
X
XGood luck with this. Please let me know if you find any flaws in
Xthe above or come across any other problems I haven't seen yet;
Xother than that, I make no guarantee or warranty whatsoever for this
Xsoftware. Use at your own risk and let the user beware!

X# A successful connection that results in say a half hour conversation
X# and then terminates abnormally will retry - it would be better to let

X# 27-Mar-89 Modified to check number of inodes and blocks before doing
X# the uucico. Aborts and sends warning message to console and unix.log
X# if either is too low.
X# 27-Apr-89 Removed debugging stuff used to test null poll file operation.
