be installed as a TSR after NGENWAN.SYS. 4000API.EXE must have the /C3
switch set, which tells 4000API.EXE to treat COM3 calls as COM3 instead of
COM1 with no modem control signals.
DOS applications require only NORAPM.EXE for proper operation of
NGENWAN.SYS. NORAPM.EXE must be installed as a device driver in
CONFIG.SYS prior to the installation of NGENWAN.SYS. DOS applications
that need to use 4000API.EXE with NGENWAN.SYS must install 4000API as a
TSR after NGENWAN.SYS is installed. 4000API.EXE must have the /C3 switch
set, which tells 4000API.EXE to treat COM3 calls as COM3 instead of COM1
with no modem control signals.
Qualifying Wireless WAN Cards
Several PC Card Wireless WAN cards have been tested with NGENWAN and are
known to contain a valid CIS that allows NGENWAN to properly enable/disable
the Wireless WAN PC card. The IBM ARDIS, IBM CDPD, and ERICSSON
MOBIDEM cards do qualify.
This information is constantly changing as new cards become available. For
information on the latest qualifying PC Card Wireless WAN cards, call the
Customer Support Center at 800Ć755Ć5505 (U.S.A. or Canada) or 425Ć356Ć1799.
"
NOTE:
See page 2-24 for application interfaces and device behavior information. Be sure to make
“modem” to “wireless WAN card” changes where necessary.
While the wireless WAN card driver is opened, it is possible to SUSPEND the
system. The behavior of the network card during suspend is based on the device
driver's -O option.
"
If the -O option is set active, the driver removes all power (Vcc, Vpp and
POD2) during suspend. It is the responsibility of the application or
middleware to open the driver and reinitialize the COM port settings after
power is restored. If the -O option is set active, the -R option has no effect.
"
If the -O option is set inactive, all power (specified by -V and -P options)
remains on during suspend. If the -R option is also set active, the STSCHG
PC Card pin causes the HHC to resume and the driver is not reset or does
not reinitialize the radio on resume. If the -R option is inactive, then the
radio cannot resume the HHC, but can still receive and buffer messages.
The wireless WAN card driver configuration is specified on the device driver
command line. The socket, COM port, driver name and system IRQ are global
system resources. No other PC Card can use these system resources.
"
NOTE:
The driver owns the slot and only a wireless WAN card device can exist in the socket.
See page 2Ć25 for supported DOS driver IOCTL_IN functions. Be sure to make
modem" to wireless WAN card" changes where necessary.
Interrupts Supported by NGENWAN.SYS
The 4000 Series interrupts supported by NGENWAN.SYS are identified by the
symbolic notation,
NGENWAN
.
The INT 14h function, Turn Wireless WAN Card Power Off/On, is intercepted
and processed entirely by the driver when DX + 1 equals the COM port specified
on the driver command line.
"
NOTE:
See page 2-28 for INT 14h and INT 15h information.
