MT2834ZPX Owner's Manual
Some connect when the software loads and remain connected
until the program terminates. Others, like MultiExpress Terminal,
can disconnect without exiting the program (make sure the
Connect icon looks plugged in). MultiExpress Terminal also allows
multiple terminals to be open, but only one can access the modem
at a time. If MultiExpress Terminal reports that it cannot make a
connection, click on the Window menu to see if more than one
terminal is open.

Your communications software settings may not match the port
the modem is connected to. Or you may have selected a COM
port in your software other than the one the modem is connected
to—compare the settings in your software to the connection.
•
Peripheral expansion cards, such as bus mouse and sound cards,
may include a serial port preconfigured as COM1 or COM2. The
extra serial port, or the card itself, may use the same COM port,
memory address, or interrupt request (IRQ) as your
communications port. Be sure to disable any unused ports.
To look for address or IRQ conflicts if you use Windows 3.1x,
select File, Run in Program Manager, type MSD, and press
ENTER. Then select Mouse, COM Ports, and IRQ Status and note
the addresses and IRQs that are in use. If you find an IRQ
conflict, note which IRQs are not being used, then change one of
the conflicting devices to use one of the unused IRQs. If you find
an address conflict, change the address of one of the conflicting
devices.
To change a port address or IRQ in Windows 3.1x, double-click
the Control Panel icon, then the Ports icon. Click on the port you
want to change, click Settings, click Advanced, and select the new
port address and/or interrupt. If you wish to use COM3 or COM4,
note that COM3 shares an IRQ with COM1, as does COM4 with
COM2, so you should change their IRQs to unused ones, if
possible.
If you use Windows 95, right-click on
My Computer

Communications
Port
your modem is connected to. In the port’s
Properties
sheet,
click on 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 will appear in the Conflicting Device List.
