UMODEM(4)		     Kernel Interfaces Manual		       UMODEM(4)

NAME
     umodem -- USB modem support

SYNOPSIS
     umodem* at uhub?
     ucom*   at umodem?

DESCRIPTION
     The  umodem driver provides support for USB modems in the Communication De-
     vice Class using the Abstract Control Model.  These  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 separate pipes.  In the latter case
     the AT commands have to be given on device separate from the data device.

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

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.
