up. On some machines MSD will not show what COM port was
configured for the PRO/100 PC Card. If it doesn’t, try the
following command:
ECHO ATDTNNNNNNN > COMX:
where nnnnnnn is a telephone you can hear ring, and x is the COM
port number. If the phone rings, this indicates that the COM port is
correctly configured and that the modem is able to dial.

keyword in the LAN configuration file. You should also modify the
SYSTEM.INI file as follows: set COMxIRQ=y, where x is the
COM port the PRO/100 PC Card is configured as, and y is the
interrupt the LAN driver is using (as stated in the NET.CFG or
PROTOCOL.INI file).
2 If you are using the M16BODI driver and you receive a blue
warning screen stating that “A hardware interrupt has occurred,” try
adding the following section to the SYSTEM.INI file:
[VIPX]
VIRTUALIZE IRQX = OFF
where x is the interrupt number (in hexadecimal notation) used by
the M16BODI driver.
