FClass

FCLASS is the name of the Zetafax device driver that is used to control fax modems. Hence FCLASS-1 is the default name of the first fax modem attached to the Zetafax server.

Note: The number after the device name does not relate to the fax service class of the modem. For example, a Zetafax server that has been configured to use 4 fax modems would have drivers named (by default), FCLASS-1, FCLASS-2, FCLASS-3 and FCLASS-4.
