Did anyone catch the comment I had about modem hangs I see?  6.20b6
ROMs.

Occasionally, the modem will go catatonic, and neither DTR drop
nor "+++" will wake it up.  It *appears* to be dialins that drop
early, perhaps even before mgetty has sent the ATA.  My Zyxel
contact (George van der Bunte at OCOMP Canada), suggested that the
modem may be listening for CND (I have CND enabled) or EDR (is that
what it's called?) tones which never come, and isn't listening to the
RS232 port.  I haven't noticed what state CTS is in.

Last time this occured, I tried dialing in to the modem using
an ordinary telephone, and that cleared the problem.
