GeoPort: Won‘t Answer Incoming Calls In Originate Mode (4/94)

I want my GeoPort adapter to answer an incoming call in "originate" mode. It works with my external modems - that is I issue an "ATDT" command when the phone is ringing and the modem grabs the incoming call. With the GeoPort, I get a port in use error.

With the Express Modem and GeoPort, there is a time delay of 6 seconds between when a ring is detected and when you can issue a an "ATDT" command. The way to eliminate this would be to type "ATH1DT" instead of "ATDT". The "H1" forces the modem to go off-hook. Once off-hook, the "DT" command can be issued causing the modem to think it is the originator.
