Manually Answering a Call
The best way to answer a call is to set the Auto-Answer Ring
Number register (S0) to 1 or more rings. To enable this feature,
set the value of S0 to 1 or more rings.
If S0 = 0 (which is the setting from the factory), use the A
command to manually answer incoming calls, as follows:
TYPE:
ATA (after the modem rings)
PRESS: Enter
NOTE:
DTR must be present (activated by the communications
software) for the modem to answer the call.
Using the Escape Sequence —
Switching Between Data Mode
and Online Command Mode
To enter online Command mode while in Data mode, use the
escape sequence, which consists of three plus signs (+++).
When typing the escape sequence, you must allow some
amount of idle time before and after typing the + signs. This
amount of time is called the escape guard time. For example, if
the escape guard time is set for one second (the setting from the
factory), you must allow at least one second of idle time (no data
being transferred) before typing the first + sign, and at least one
second after typing the last + sign, before the modem will be in
online Command mode. Further, you must not wait more than
one second between typing each of the three + signs.
This idle time before and after the escape sequence prevents
the escape sequence characters from being misinterpreted as
part of the data stream being sent between the modems.
To enter the escape sequence:
TYPE:
+++
Do not press the Enter key. The modem enters
online Command mode and responds with an OK.
