+.Sh NAME
+.Nm umodem
+.Nd USB modem support
+.Sh SYNOPSIS
+.Cd "umodem* at uhub?"
+.Cd "ucom*   at umodem?"
+.Sh DESCRIPTION
+The
+.Nm
+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.
+.Pp
+The device is accessed through the
+.Xr ucom 4
+driver which makes it behave like a
+.Xr tty 4 .
+.Sh SEE ALSO
+.Xr tty 4 ,
+.Xr ucom 4 ,
+.Xr usb 4
+.Sh HISTORY
+The
+.Nm
+driver
+appeared in
+.Nx 1.5 .
+This manual page was adopted from
+.Nx
+by Tom Rhodes <trhodes@FreeBSD.org>
+in April 2002.
+.Sh BUGS
+Only modems with multiplexed commands and data are supported
+at the moment.
