umodem
— USB
Communication Device Class serial (CDC ACM) driver
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"
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).
Devices supported by the umodem
driver
include:
The umodem
driver appeared in
NetBSD 1.5. This manual page was adopted from
NetBSD by Tom Rhodes
<trhodes@FreeBSD.org>
in April 2002.
Only modems with multiplexed commands and data are supported at the moment.
