[net.micro.68k] Getting around the Tandy Device Dri

gm@trsvax (11/26/85)

If you have System III (Xenix 3.0), in /usr/lib/uucp there are several
files and commands to aid in getting a non-RS modem to work with 
uucico and cu.s3 .  The files are:

dial		- The default dialer program (linked to dialTRS)
dialHAYES	- dialer for the Hayes 300/1200/2400, etc.
dialVADIC	- dialer for Radcal-Vadic modems
dialTRS		- dialer for Radio-Shack modems (linked to dial)
dial.c		- source to the Hayes dialer, which should be easy to modify
link_dial	- a shell script to compile and link any new dialers you 
		  may write.

So if you have a Hayes (or Hayes-clone) modem, just re-link dial to
dialHAYES and change the L-devices entries to /dev/ttyxx rather than
/dev/cuxx.

One of the problems you may have been having is the fact that the default
cu (/bin/cu) is actually the Version 7 cu. This does not support non-RS
modems; however, cu.s3 (the system III cu) does use /usr/lib/uucp/dial
to figure out what to tell the modems. The reason we distribute two cu's
is the fact that the System III cu will grab whatever the first matching
device in /usr/lib/uucp/L-devices and use that baud rate, reguardless
what you told it on the command line. So when you re-link for another
modem, you need to re-arrange L-devices so that the baud rate you will
be using most often is at the top.
