UMSM(4)                  BSD Kernel Interfaces Manual                  UMSM(4)

     umsm -- Qualcomm MSM modem device

     umsm* at uhub?
     ucom* at umsm?

     The umsm driver supports Qualcomm MSM modem adapters.  The MSM chipset is
     found in EVDO, UMTS and LTE 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/HSUPA modems have three serial ports, but only the last
     port can be used to make PPP connections.  The Medion Mobile S4222 has
     four serial ports, but only the first port can be used to make connec-

     Some modems require multi-link PPP operation.  For example, the Huawei
     E1550 has four serial ports.  When initiating a connection, the control
     commands have to be issued on the third port, and after that the actual
     PPP connection comes up on the first port.  The function of the second
     and fourth ports is unknown.

     An example demand dial configuration for Cingular Wireless using pppd(8):


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


           user ispATcingulargprs.com
           active-filter 'not udp port 123'
           idle 600
           connect "/usr/sbin/chat -v -f /etc/ppp/cingular-chat"


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

     pppd(8) is then started using:

           # pppd call ac875

     ucom(4), uhub(4), usb(4), pppd(8)

     The umsm device driver first appeared in OpenBSD 4.0.

     The umsm driver was written by Jonathan Gray <jsg@openbsd.org> and Yojiro
     UO <yuo@nui.org>.

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

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