.Sh SYNOPSIS

|
.Cd "umodem* at uhub?"
|
|
.Pp
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
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 multiplxed 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.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver shows a behaviour like a
|
|
.Xr tty 4 .
|
|
This means that normal programs such as
|
|
.Xr tip 1
|
|
or
|
|
.Xr pppd 8
|
|
can be used to access the modem.

|
|
at the moment.
