The 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 chapter 9. 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. Following are the fax-related AT commands: Mode Settings #F + #B0 #B1 #B2 #B3 Sets the modem into V17G3 FAX mode; same function as the extended AT command AT&N32. Sets the fax receiving mode. The connection parameters and received fax data are sent to the DTE continuously following the connect message. (Default) Sets the fax receiving mode. The connection messages are separated from the received fax data. The modem sends CONNECT FAX and ZyXEL first, then it waits for the DC2 character (hex18) to send the fax data. When the modem receives a DC2 from the DTE, it starts to send the fax connection parameters /SnnnnVnTnRnLnCnP and then the received fax data. In this mode, the modem will wait for a DC2 at the beginning of every page. The DTE software should detect the page separator RTC and then sends the DC2 to receive the next page of fax data. This mode is used with a BBS receiving faxes. This mode is for the polling feature of the modem. In this mode, the modem will send a polling signal to the remote fax device to ask to receive a fax from the remote fax device. The received fax data will be sent to the DTE continuously following the connection message. Displays the ring cadence.
