Both modems didn't that AT&C1 or just the 1200? If the modem doesn't accept AT&C1, then you'll need to set IgnoreDCD = TRUE in the sexpots.ini file used for that modem.

Wouldn't the HSM 300 be older than the 1200? I'd be very suprirsed if an older (300bps?) modem supported AT&C1 while the newer modem (1200bps?) did not.

Weird. Anyway, telling SexPOTS to ignore DCD should work around *that* modem issue.
