UMODEM(4)	       FreeBSD Kernel Interfaces Manual		     UMODEM(4)

NAME
     umodem -- USB modem support

SYNOPSIS
     device umodem
     device ucom

DESCRIPTION
     The umodem	driver provides	support	for USB	modems in the Communication
     Device Class using	the Abstract Control Model.  These modems are basi-
     cally standard serial line	modems,	but they are accessed via USB instead.
     They support a regular AT command set.  The commands can either be	multi-
     plexed with the data stream or handled through separate pipes.  In	the
     latter case the AT	commands have to be given on a device separate from
     the data device.

     The device	is accessed through the	ucom(4)	driver which makes it behave
     like a tty(4).

HARDWARE
     Devices supported by the umodem driver include:

     +o	 3Com 5605
     +o	 Metricom Ricochet GS USB wireless modem
     +o	 Yamaha	Broadband Wireless Router RTW65b

SEE ALSO
     tty(4), ucom(4), usb(4)

HISTORY
     The umodem	driver appeared	in NetBSD 1.5.	This manual page was adopted
     from NetBSD by Tom	Rhodes <trhodes@FreeBSD.org> in	April 2002.

BUGS
     Only modems with multiplexed commands and data are	supported at the
     moment.
