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"
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).
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.
