.Sh NAME
.Nm umsm
.Nd Qualcomm MSM modem device
.Sh SYNOPSIS
.Cd "umsm* at uhub?"
.Cd "ucom* at umsm?"
.Sh DESCRIPTION
The
.Nm
driver supports Qualcomm MSM modem adapters.
The MSM chipset is found in EVDO and UMTS capable modems.
Typically these are CardBus and PCI Express Mini Cards that incorporate a
USB controller with the actual device attached to it.
.Pp
The following devices are known to work with the
.Nm
driver:

.Pp
Some modems have multiple serial ports,
however almost all modems have only one effective serial port
for PPP connections.
For example, the Huawei E220 has two serial ports,
but only the first port can be used to make connections;
the second one is for management.
The Option GlobeTrotter HSDPA modem has three serial ports,
but only the last port can be used to make PPP connections.
.Sh EXAMPLES
An example
.Pa /etc/ppp/ppp.conf
configuration for Verizon Wireless might look something like below;
see
.Xr ppp 8
for more information.
.Bd -literal -offset indent
default:
   set device /dev/cuaU0
   set speed 230400
   set dial "ABORT BUSY ABORT NO\e\esCARRIER TIMEOUT 5 \e
             \e"\e" AT OK-AT-OK ATE1Q0s7=60 OK \e\edATDT\e\eT TIMEOUT 40 CONNECT"
   set phone "#777"
   set login
   set authname 4517654321@vzw3g.com
   set authkey vzw
   set timeout 120
   set ifaddr 10.0.0.1/0 10.0.0.2/0 255.255.255.0 0.0.0.0
   add default HISADDR
   enable dns

.Pp
In this example the phone number is (451) 765-4321: replace this with
the number issued for the card or your phone's number if a handset is being
used.

.Sh HISTORY
The
.Nm
device driver first appeared in
.Ox 4.0 .
.Sh AUTHORS

The
.Nm
driver was written by

and

.Sh CAVEATS
For Verizon Wireless (and possibly other services),
cards require a one-time activation before they will work;
.Nm
does not currently support this.
