UMODEM(4) FreeBSD Kernel Interfaces Manual UMODEM(4) NAME umodem -- 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 ALSO tty(4), ucom(4), uhub(4), usb(4) HISTORY The umodem driver appeared in NetBSD 1.5. OpenBSD support was added in OpenBSD 2.7. BUGS Only modems with multiplexed commands and data are supported at the mo- ment. FreeBSD 13.0 June 26, 2008 FreeBSD 13.0
