UMODEM(4)		    Kernel Interfaces Manual		     UMODEM(4)

NAME
       umodem -- USB Communication Device Class	serial (CDC ACM) driver

SYNOPSIS
       To  compile  this  driver into the kernel, place	the following lines in
       your kernel configuration file:

	     device usb
	     device ucom
	     device umodem

       Alternatively, to load the driver as a module at	boot time,  place  the
       following line in loader.conf(5):

	     umodem_load="YES"

DESCRIPTION
       The  umodem  driver  provides support for USB modems and	serial devices
       that implement the Communication	Device Class  Abstract	Control	 Model
       (CDC  ACM).   It	 also provides device-side CDC ACM support.  Supported
       modems are basically standard serial line modems, but they are accessed
       via USB instead.	 They support a	regular	AT command set.	 The  commands
       can either be multiplexed with the data stream or handled through sepa-
       rate  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).

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.

       Only modems with	multiplexed commands and data are supported at the mo-
       ment.
