+FCLASS=n	Service Class Selection
	Normally set by fax software, Service Class Selection determines the fax
	protocol. The command is sent to the modem in the format +FCLASS=n,
	where n can be set to one of three values:
	0=Data
	1=Class 1 Fax (EIA 578)
	2=Class 2 Fax (EIA/TIA SP-2388 dated 20 August 1990)
	In the format +FCLASS?, the +FCLASS command returns the current
	Service Class: 0, 1, or 2. In the format +FCLASS=?, the +FCLASS
	command returns the Service Classes available: 0, 1, 2.
	NOTE: Other fax commands supported by the 3800Plus modems are not
		documented in this manual because they are not normally issued
		by the user. They follow the EIA 578 and EIA/TIA SP-2388
		specifications.
