Owner’s Manual
(software designed for an older operating system), make
sure the initialization string includes
&F as the first command
to cancel any
leftover commands that could interfere with the
modem’s operation.
• If you don’t get an
OK, the problem may still be in the
communications software. Make sure you have done
whatever is necessary in your software to make a port
connection. Most legacy (prior to Windows 95)
communications programs connect to the COM port when
the software loads and remain connected until the program
terminates. Some, however, can disconnect without exiting
the program. If you have one of these, try issuing the
software’s connection command. Also, if more than one
communications program is open, they can conflict with
each other. Make sure all other communications programs
are closed and then try again.
• If you are using legacy software, it’s COM port setting may
not match the COM port Windows 95 assigned to the
modem. Compare the COM port setting in your software to
the COM port reported in the
Diagnostics tab of the
Modem’s
Properties sheet. (Select Start, Settings, Control
Panel, Modems, Diagnostics.)
• Another expansion card, such as a bus mouse or sound
card, may be using the same COM port, memory address,
or interrupt request (IRQ) as your modem. On the Windows
95 desktop, right-click
My Computer, select Properties,
Device Manager, and Ports. Then double-click the
Communications Port your modem is connected to.
In the port’s
Properties sheet, click the Resources tab to see
the port’s Input/Output range and Interrupt Request. If another
device is using the same address range or IRQ, it appears in
the
Conflicting Device List. Remove the check for Use
Automatic Settings to change the port’s settings, so they do not
conflict with the other device.
Or select the port the conflicting device is on and change it
instead. If you need to change switches or jumpers on the
conflicting device, refer to the device’s documentation.
