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 umodem

       Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

             umodem_load="YES"

DESCRIPTION

       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).

HISTORY

       The umodem driver appeared in NetBSD 1.5.  This manual  page  was  adopted  from  NetBSD  by  Tom  Rhodes
       <trhodes@FreeBSD.org> in April 2002.

BUGS

       Only modems with multiplexed commands and data are supported at the moment.
