UMSM(4)                   OpenBSD Programmer's Manual                  UMSM(4)

NAME
     umsm - Qualcomm MSM modem device

SYNOPSIS
     umsm* at uhub?
     ucom* at umsm?

DESCRIPTION
     The umsm driver supports Qualcomm MSM modem adapters.  The MSM chipset is
     found in EDVO 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.

     The following devices are known to work with the umsm driver:

           Device                           Bus
           AirPrime PC5220                  CardBus
           Kyocera KPC650                   CardBus
           Sierra Wireless MC8755           PCI Express Mini Card

     Devices suspected of being compatible are:

           Device                           Bus
           Dell W5500                       PCI Express Mini Card
           Novatel Wireless Merlin V620     CardBus
           Novatel Wireless S720            CardBus

           Novatel Wireless XU870 HSDPA     ExpressCard
           Sierra Wireless AirCard 580      CardBus
           Sierra Wireless AirCard 595      CardBus
           Sierra Wireless AirCard 875      CardBus
           Sierra Wireless EM5625           USB module
           Sierra Wireless MC5720           PCI Express Mini Card
           Sierra Wireless MC5725           PCI Express Mini Card
           Sierra Wireless MC8765           PCI Express Mini Card
           Sierra Wireless MC8775           PCI Express Mini Card

EXAMPLES
     An example /etc/ppp/ppp.conf configuration for Verizon Wireless might
     look something like below; see ppp(8) for more information.

           default:
              set device /dev/cuaU0
              set speed 230400
              set dial "ABORT BUSY ABORT NO\\sCARRIER TIMEOUT 5 \
                        \"\" AT OK-AT-OK ATE1Q0s7=60 OK \\dATDT\\T 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

     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.

HISTORY
     The umsm device driver first appeared in OpenBSD 4.0.

AUTHORS
     The umsm driver was written by Jonathan Gray <jsg@openbsd.org>.

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