Fax Reception from a BBS

The U-336S/SA can automatically detect data and fax calls and allow BBS software to receive faxes on the same phone line. To allow your BBS to receive incoming faxes, make the following set-up changes in your BBS:

1.Add the string #B1+FCLASS=6 to the init string. Be sure the +FCLASS=6 command is the last command.

2.Change one of the messages in the list to CONNECT FAX.

3.Set the external mail string to ZyXEL and give it an error level.

4.In your BBS batch file, if the error level matches the external mail, execute

rcvfax 2 /p:comport [/w:workpath]

This setting will enable the BBS to receive a fax and store it automatically.

The following is a sample setting for the FrontDoor system.
