NAME    [Toc]    [Back]

     umodem -- USB modem support

SYNOPSIS    [Toc]    [Back]

     umodem* at uhub?
     ucom*   at umodem?

DESCRIPTION    [Toc]    [Back]

     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 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    [Toc]    [Back]

     tty(4), ucom(4), usb(4)
