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 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.

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

     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 Globe-
     Trotter HSDPA modem has three serial ports, but only the last port can be
     used to make PPP connections.

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 4517654321ATvzw3g.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.

     An example demand dial configuration for Cingular Wireless using pppd(8)
     appears below.

     /etc/ppp/cingular-chat:

           TIMEOUT 10
           REPORT CONNECT
           ABORT BUSY
           ABORT 'NO CARRIER'
           ABORT ERROR
           AT+CGDCONT=1,"IP","isp.cingular" OK
           ATD*99***1# CONNECT

     /etc/ppp/peers/ac875:

           cuaU0
           115200
           debug
           noauth
           nocrtscts
           :10.254.254.1
           ipcp-accept-remote
           defaultroute
           user ispATcingulargprs.com
           demand
           active-filter 'not udp port 123'
           persist
           idle 600
           connect "/usr/sbin/chat -v -f /etc/ppp/cingular-chat"

     /etc/ppp/chap-secrets:

           # Secrets for authentication using CHAP
           # client                server  secret          IP addresses
           ispATcingulargprs.com    *       CINGULAR1

     pppd(8) is then started using:

           # pppd call ac875

HISTORY
     The umsm device driver first appeared in OpenBSD 4.0.

AUTHORS
     The umsm driver was written by Jonathan Gray <jsgATopenbsd.org>, and
     Yojiro UO <yuoATnui.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.

     The additional IEEE 802.11 wireless chipset found in the Option Globe-
     Trotter GT FUSION is not yet supported.
