Command Descriptions
A Answer
The A command causes the modem to connect to the
telephone line and issue a carrier. If you are using the
established telephone connection for voice
communications and then want to switch your
system to data mode to communicate with the other
party's system, you must use this command in the
following way:
1. Have the other party enter AT D on their
system without entering a phone number.
2. Enter ATA on your system within a few
seconds. Both parties can hang up the phone.
The modem sends a CONNECT result
message when the connection occurs.
