NAME
umodem —
USB modem support
SYNOPSIS
umodem* at uhub?
ucom* at umodem?
DESCRIPTION
Theumodem 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 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).

HISTORY

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