NAME

     umodem -- USB modem support

SYNOPSIS

     To compile this driver into the kernel, place the following lines in your
     kernel configuration file:

           device umodem
           device ucom

     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 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).
