This is not a handshake problem. It is a dialing problem. When you type
"ATDTxxxxxxxxxx" on a Hayes compatible modem, it dials. (where xxxxxxxxxx is
the telephone number)

Here's the story. I got rid of my land line. Now I can't use my old Zoom
2949L and Hyperterm to connect to the VT100 port anymore. So I am trying to
use the modem in my cell phone with Hyperterm. I have been using Hyperterm
with my land line to access this VT100 port for over 10 years without a
problem. Now I have only a cell phone and no land line.

As far as modems go, this should work. But when I type "ATDTxxxxxxxxxx" in
Hyperterm I immediately get "ERROR" as the response. This same command
worked fine with my land line and the Zoom modem.

I have tried typing ATX0 <CR> and get an "OK" followed by ATDTxxxxxxxxxx
<CR>, but just get ERROR in response.

Keep in mind that the cell modem does respond to some AT commands, but not
the one I need to dial out.

I just want to know what AT command I need to use to dial out...and one that
works with this cell phone.

Thanks again,

David
