[comp.dcom.modems] modem offhook at powerup?

EP.BIO@forsythe.stanford.edu (Charles Allen Smith) (02/13/90)

I recently transferred a Hayes 2400 Baud modem from a PC to
an XT. No problems before; now I often get the modem coming on
(opens connection and gets dial tone) within a few seconds of
powering on the computer. Rapidly switching power off and back on
usually cures this. When it is "off hook" in this way I can't
communicate with the modem via AT commands. The modem is on com2
via the switch on the card, com1 is the port on an old AST memory/
port add-in.
I assume this is a computer hardware problem since it never happenned
before, but I don't know what could be waking up the modem so
soon after power on. Anyone encountered this or know a workaround?
I don't use it extensively; some routine to reset it would be fine.
Thanks,
Allen Smith
