NAME
     umodem -- USB modem support

SYNOPSIS
     umodem* at uhub?
     ucom*   at umodem?

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
     multiplexed 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).

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

HISTORY
     The umodem driver appeared in NetBSD 1.5.

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