[comp.unix.xenix] Setting modem to answer on 4 rings

gritchie@polyslo.CalPoly.EDU (Gary Ritchie) (08/08/90)

	Thanks for all the help on my last problem with the monochrome
monitor.  I've run into another problem I can't figure out.  I'm
trying to get my modem to answer on the fourth ring.  I have changed
the dialers file to ATS0=4 in the string that resets auto answer.
However, the modem is reinitialized to 1 ring answer.  
	Next I changed the reinit string to S0=0 to turn off the modem
from answering.  No change.  The modem still answers on 1 ring.  Is
the modem being reset by something other than the dialers file, and
if so, is there anything I can do to change it.
	I'm running XENIX 386, the most current version, have the modem
set up for tty2A, and the modem is a Hayes 2400.  I used to have 
this working on XENIX 286 which was controlled by the dialers
file.  Any suggestions?

thanks,
-gary

The problem is that the modem is being re-initialized by the program

		/usr/lib/uucp/dialHA24

(assuming a Hayes 2400).  You have to modify this program and then recompile
it on your system.

As I recall, the dialer used is in the fifth field of the Devices file entry.
It first looks for a binary by that name in /usr/lib/uucp, then it searches the
Dialers file.

If your Devices entry looks like:

       ACU ttyA7 - 300-2400 dialHA24

change it to:

       ACU ttyA7 - 300-2400 hayes2400

If it is already hayes2400, I suspect your modem is resetting itself on DTR
transition. You could connect directly to the modem with 

       cu -lttyA7 dir

issue the ATS0=4&W command to write the desired setting into memory.
