Extended Fax AT Command Set
Extended Fax AT Commands are unique to ZyXEL modems. The
computer controls the modem through a set of extended fax AT
commands and the modem responds with a set of status report result
codes. During
data state, compressed fax image data is flowing
between the modem and
computer. The default serial connection speed
is 38400 bps, and it is higher than the fax link rate. CTS/RTS hardware
flow control is used to regulate the data flow.
Your modem accepts the extended fax AT commands to set the
modem mode and fax parameters. Besides the extended fax AT
commands, the modem accepts all the other AT commands described
in this chapter. For instance, you can use ATD to make a fax call, or
ATA to answer an incoming fax call. When using the extended Fax AT
commands, you need to send the command AT+FCLASS=6 first.
