Thank you for responding Mirek, I really appreciate it.


>Allways try recent (1.1.18) version of mgetty (because 1.1.xx are

I have been chasing the version monster for the last year and a half.
I will try 1.1.18 if you really think it is necessary.

>Send your modem configuration (start minicom and write: atl5l6l7)

Is this really a lower case L as in ATL5L6L7? The string^^^^^^^^
didn't work just reported an error with atl5l6l7 and atl5 atl6 atl6.

or is it ati5, ati6, ati7?

I'm sorry I am not well versed in minicom.  I am much more comfortable
with cu.  Here is a session from cu with ati.

Connected.
atz
OK
ati5i6i7
1.01,0,19

OK
ati5
1.01,0,19

OK
ati6
OK
ati7
OK

Is there something that I am missing?  I can't seem to find anyway
to get to the configuration on these MultiTechs.  The USRs will report 
all the info by using ati5 ati6 ati7.

The serial line speed is set at 57600 as per MultiTech.
If I change this to 38400 will this decrease the throughput?
Or should I go higher, 115200?  The cables that go to these modems
are the flat cables that were supplied cyclades.  Could these be the 
culprit?


I noticed that my mgetty.config file has this at line 20:

# access the modem(s) with 38400 bps
speed 38400

This should probably be 57600?  Since my mgetty lines in inittab have
-s 57600

Excuse me for being slow, what $SB?

>and modem doesn't reset because wrong &D setting.
>Use minicom and write:

This is what I have done to all the modems for the last year and a half.

cu -l ttyCxx
atz
atm0
at&d3
atx1
at&w0
atz
~.

Is this in the policy.h?  The line #309:

#define MODEM_INIT_STRING       "ATS0=0Q0&D3&C1"
