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).
