[comp.dcom.modems] Help! Modem and Terminal server lock up

     Hi...I,m new to this newsgroup but I am looking for some help with 
a modem problem...Any help would be appreciated.

	We have six Telebit T2500 baud modems connected to a 
Xylogics Annex II terminal server.  Five of these are configured
as dial in only and one has been set up for outbound calls.
The ones set for dial in only work fine but the outbound occasionally
locks up.  Apparently the terminal server drops dtr to the modem and the
process for that port dies.  The only way we've found to get the
terminal server to restart the port is to reboot the entire Annex.
Resetting the port for the modem doesn't work.  If anyone has
had similar problems with the Annex connected to a modem, please
let me know.

		Thanks.
