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 basically standard serial line modems, but they are accessed via

USB instead.
They support a regular AT command set. The commands can ei

ther 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).

HARDWARE

Devices supported by the umodem driver include:

+o 3Com 5605
+o Metricom Ricochet GS USB wireless modem
+o Yamaha Broadband Wireless Router RTW65b
+o ELSA MicroLink 56k USB modem
