UMODEM(4) FreeBSD Kernel Interfaces Manual UMODEM(4)
NAME
umodem - USB Communication Device Class serial (CDC ACM) driver
SYNOPSIS
To compile this driver into the kernel, place the following lines in your
kernel configuration file:
device usb
device ucom
device umodem
Alternatively, to load the driver as a module at boot time, place the
following line in loader.conf(5):
umodem_load="YES"
DESCRIPTION
The umodem driver provides support for USB modems and serial devices that
implement the Communication Device Class Abstract Control Model (CDC
ACM). It also provides device-side CDC ACM support. Supported 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).
