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/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 connections.
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.

EXAMPLES

An example demand dial configuration for Cingular Wireless using pppd(8):
/etc/ppp/cingular-chat:
TIMEOUT 10 
REPORT CONNECT 
ABORT BUSY 
ABORT 'NO CARRIER' 
ABORT ERROR 
'' ATZ OK AT&F OK 
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 isp@cingulargprs.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 
isp@cingulargprs.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 <jsg@openbsd.org> and Yojiro UO <yuo@nui.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 GlobeTrotter GT FUSION is not yet supported.
