Answering a Call
You can answer incoming calls to the TA either manually or automatically. When the TA
detects an incoming call, it sends a RING result code to the computer or terminal after
each ring. If autoanswer is enabled, the TA automatically answers the call. You can
manually answer the call with the A command. Both methods are described below.
Answering Manually
If your communication program is in terminal mode when the RING result code appears
on your monitor, you can manually answer the call by typing ATA <cr>.
Answering Automatically
To cause the TA to automatically answer a call:
1. Enable autoanswer by setting register S0 to the ring on which you want the TA to
2. Make sure that the TA is offline.
The TA answers the call after the number of rings specified by S0. To disable
autoanswer, use a configuration utility or the command S0=0.
Note:
Hanging Up
To hang up a call, escape to online command mode (+++AT<cr>), then enter the H
command (ATH<cr>). The escape sequence and hang up command can be combined
into one command string: +++ATH<cr>.
60
answer (e.g., in terminal mode, type S0=4 to make the TA answer on the fourth ring).
You also can use either of the configuration utilities to the turn on autoanswer and set
the number of rings.
