Using the Internal Modem

Basic operation

Receiving a call

To set the number of rings before the internal modem automatically answers the phone, set the S0 register as follows:

ATS0=* and press Enter.

The asterisk * indicates the number of rings.

See “S-Register values” on page 82 for more details.

Terminating a call

The methods for terminating a call depend on the status of the connection.

If the internal modem is dialing or has not yet gone online, you can terminate a call by pressing any key.

If the terminal is online, enter the escape code (+++), then type: ATH and press Enter.

If the remote party disconnects, the call will be automatically cut off.

If the power to the computer is cut off, the call is terminated.

Setting the data flow control

Data flow control is used to start and stop data transmission according to the status of the data buffer (full or empty). The following describes how to set the data flow control method:

CTS/RTS (hardware control)

XON/XOFF (software)
