User's Guide for ZyXEL Omni 56K USB Modem

COMMAND	DESCRIPTION
+FMINSP=n	Minimum phase C speed parameter:

VALUE

	2400 bps.	n=0
	4800 bps.	n=1
	7200 bps.	n=2
	9600 bps.	n=3
	12000 bps.	n=4
	14400 bps.	n=5
+FPHCTO=	DTE Phase C response time-out:	0 to 255
<value>	Determine how long the DCE waits for a command after reaching
	the end of data when transmitting in Phase C.
	<value>=0 to 255; 100 ms units.
+FPTS=n	Page transfer status:
	Received page good.	n=1
	Page bad; retrain requested.	n=2
	Page good; retrain requested.	n=3
	Page bad; procedure interrupt requested.	n=4
	Page good; procedure interrupt requested.	n=5
+FREL=n	Phase C received EOL alignment:
	The EOL patterns are bit aligned as received.	n=0
	The last received bits of EOL patterns are byte aligned by the	n=1
	DCE, with necessary zero fill bits inserted. Refer to TIA
	(Telecommunications Industry Association) PN-2388 for details.
+FREV?	Request the DCE revision identification.
+FSPL=n	"Enable polling" command:
	Disable polling.	n=0
	Enable polling.	n=1

All other +F commands are not supported, but the modem responds OK. In many cases this means "it is ignored”.
