I have two different modems that after some use (with a very
noisy line) get locked. Not even lowering the DTR (for up to 2 seconds) will
reset them. Yes, at&d3 is set. When one of them get locked I tried:
lowering the DTR (for up to 2 seconds, just in case since ats25=2)
The only way to unlock it is to reboot (ouch!).
They are on a 486 running linux 1.3.77 with mgetty 0.99Dic31. They
are connected as COM3 & COM4. COM1 & COM2 are disabled.
Here is some info about them:
ati4 V.32bis/FAX MODEM. S/W Version 5.10
at+frev? CEP-03 3/15/94
ati6 RC144DPi Rev CA
I'll be grateful if someone could provide with any other ideas on how to
unlock them. Thanks in advance,
