I whipped up this stuff to make dealing with PC Pursuit for UUCP connections
a little easier; hopefully it will benefit other Microport users out on the
net.
Enjoy!

XFollowing are my kludges for Microport uucp to make it work with PC Pursuit a
Xlittle more gracefully.
X
Xpcpdial - This is a dialer script which will interact with PC Pursuit.
XIt takes its arguments from the L-devices file. An L-devices line should
Xbe made for each site you wish to call through PC Pursuit along with a
Xlink in /dev to the dialout port you wish them to use. For example, to call
XMicroport:
X
XDIR uportd pcpdial 408 4381680
X
Xuucico.c - Just a front-end for uucico.sh so that uucico.sh can be run setuid
Xuucp.
X
Xuucico.sh - This goes around uucico and implements additional locking. Since
Xthere are multiple names for the dial-out line, uucico, left to its own
Xdevices, could try to dial two systems on the same line, thinking that it
Xwas two different devices. This script has the PC Pursuit system names
Xhardcoded into it and for these systems checks for a lock on the real port
Xname, and if there is not one creates it. It then calls the renamed
Xuucico to place the call, then removes the lock file when it returns.
X
Xlock.c - Does a lock on a file atomically.
X
Xpcptime.c - This checks to see if it's OK to make a PC-Pursuit call. Not
Xreally necessary, but it cuts down immensely on the amount of trash
X(CAN'T CALL XXX - WRONG TIME) messages in the LOGFILE.
X
XWhy not just have a dialinfo script? Well, problem number one is that a
Xdifferent dialer script needs to be called to use PC Pursuit than to make
Xa local call. System V uucp only allows for DIR and ACU type devices.
XSo, we can't make a PCP device. We could, however, have different speeds
Xcall different dialer scripts (1200==PCP, 2400==normal dialer). Problem two
Xis that the PCP dialer needs to know what area code it is calling and the
Xdialinfo script cannot parse that out of the phone number uucico passes it
Xfrom the L.sys file. This leads to creating the different devices so that
Xthe area code can be passed from the L-devices file. Since the only way
Xto make certain we get the correct dialer is by making it a DIR device and
Xthen having it explicitly specifying that device in the L.sys file, we
Xhave to also pass the phone number from L-devices, so instead of having a
XL-devices entry for each area code, we must have an entry for each system
Xwe call and a device for each system.
X
XIt's kludgey, but it works.
X
XInstallation:
X
X1. Turn off cron, or stop uucp from executing somehow, or it's might get
Xvery confused while you're playing with its files.
X
X2. Go to /usr/lib/uucp and mv uucico uucico.exe .
X
X3. Compile uucico.c and lock.c and put the executables in /usr/lib/uucp owned
Xby uucp and with the setuid bit set. Compile pcptime and put it in
X/usr/lib/uucp owned by uucp (you can setuid if you like, but it doesn't make
Xa difference).
X
X4. Put uucico.sh in /usr/lib/uucp and edit it for your system. The comments in
Xthere should be self-explanatory. You need to change system names and the
Xdevice it locks.
X
X5. Add the pcpdial script into /usr/lib/uucp/dialinfo and edit in your own
XPC Pursuit account number, password and local access number.
X
X6. Edit L-devices and L.sys for those systems you want to call via PC Pursuit.
XYour entries should look something like this:
X
XL-devices:
XDIR uportd pcpdial 1200 408 4381680
X
XL.sys:
X
X# time details are taken care of by the uucico driver script
Xuport Any,1 uportd 1200 uportd "" \n\n in:-\n-in:-\n-in: nuucp
X
X7. Go to /dev and create the devices you need for your PC-Pursuit systems.
XUse ln to make links from your dialer device (e.g. /dev/tty1) to these names,
XNOT mknod.
X
X8. This should be everything. Start up a uucico to test it out and stand well
Xback in case anything blows up.
