4.0 General Operation and Special Features
place the handset back on the cradle. The LCD displays the status of the
communication. It appears as shown below.
The data link between the two modems is now established, and data transfer
begins.
An incoming call may be answered manually or automatically. To answer a
data call manually, you must disable the Auto-Answer option. Before the call
is received, the Modem must be set to TALK, as explained in the previous
section. The first unit that is switched to DATA mode must be set for answer
mode (using the answer/originate option). The other unit must be set for
originate mode.
NOTE
If you set the Modem to talk mode, the phone rings, but the Modem will
not answer, even if the Auto-Answer option is enabled.
After you answer the phone and initiate a conversation with the caller, the
Modem must be set for data mode. With the MANUAL-DIAL screen still
displayed, select DATA to put the Modem in data mode.
The first person to go to data mode hears his telephone disconnect as his
modem connects. The other person must wait until he hears an answer tone,
and then switch to data mode (select DATA). When both modems are in data
mode, the data communication begins. The LCD displays the status of the
connection.
There are several ways a data call can be terminated. You can terminate a call
through communication software by following the software manufacturer’s
instructions. An alternate method is to switch to the TALK option (talk
mode) on the MANUAL-DIAL screen, as described in the previous section.
Or you can drop the DTR signal from the DTE (by software control or by
turning the DTE off).
