UMODEM(4) BSD Kernel Interfaces Manual UMODEM(4)NAMEumodem — USB modem support
SYNOPSIS
umodem* at uhub?
ucom* at umodem?
DESCRIPTION
The umodem driver provides support for USB modems in the Communication
Device Class using the Abstract Control Model. These modems are basi‐
cally standard serial line modems, but they are accessed via USB instead.
They support a regular AT command set. The commands can either be multi‐
plexed 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).
SEE ALSOtty(4), ucom(4), usb(4)HISTORY
The umodem driver appeared in NetBSD 1.5.
BUGS
Only modems with multiplexed commands and data are supported at the
moment.
