5.18 Sending
Faxes
You can send a fax using the fax software. The commands are
automatically issued by the fax software. In case you encounter some
problems while sending or receiving a fax, refer to your fax software
manual.
Some fax packages require software flow control.
The modem uses the hardware flow control as the
factory default. You may need to enable the software
flow control to send and receive faxes.
