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 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).
SEE ALSO

ucom(4),

HISTORY
The
umodem
driver
appeared in

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