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 umodemAlternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
umodem_load="YES"
DESCRIPTION
Theumodem 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).
