USR sportster 28.800 troubles

[Tuomo Salmela <tus@kautre.aut.vtt.fi>]

 First of all, I'm sorry if this problem is an old one, but I couldn't
 find anything matching this from the archives.

 Problem is with a USR Sportster 28800, Hylafax 4.0.pl1 and Sun
 Sparcstation 10 Solaris 2.5.1. Sometimes (too frequently) the modem goes
 into a state in which it doesn't answer the phone. This occurs after
 sending an outbound fax. Modem stays in the state where only the CS led
 is on, and faxstat says 'waiting for the modem to come ready'. Resetting
 the modem with power off/on doesn't help, sometimes not even
 stopping/starting the Hylafax server processes. To fix the problem we
 have tried to send test faxes to our own fax machine and it seems to
 help, modem resets to normal condition.

 Session log from an outbound fax that hangs the modem shows no problems.
 Could I force the modem to reset after every outbound sending or is there
 something else that could be done with the problem?
