NAME    [Toc]    [Back]

     umodem - USB modem support

SYNOPSIS    [Toc]    [Back]

     umodem* at uhub? port ? configuration ?
     ucom*   at umodem?

DESCRIPTION    [Toc]    [Back]

     The umodem driver provides support for  USB  modems  in  the
     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), uhub(4), usb(4)

HISTORY    [Toc]    [Back]

     The  umodem  driver appeared in NetBSD 1.5.  OpenBSD support
was added in
     OpenBSD 2.7.

BUGS    [Toc]    [Back]

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

OpenBSD      3.6                          August     16,     1999
