can access the MTA128ST at a time. If MultiExpress Terminal reports that it

cannot make a connection, yet the MTA128STs TR indicator is on, click on

the Window menu to see if more than one terminal is open. The MTA128STs TR

indicator shows that the software has made a connection with the MTA128ST

through the COM port.

4 Your communications software settings may not match the physical port the

MTA128ST is connected to. The serial cable may be plugged into the wrong

connectorcheck your computer documentation to make sure. Or you may

have selected a COM port in your software other than the one the MTA128ST

is physically connected tocompare the settings in your software to the physi-

cal connection.

4 If the MTA128ST is on, the cable is plugged into the correct port, the communi-

cations software is configured correctly, and you still dont get an OK, the fault

may be in the serial cable. Make sure it is firmly connected at both ends.

4 Is this the first time you have used the cable? If so, check the cable description

on the packaging to make sure the cable is correct for your computer.

4 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 con-

flict, 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, select Properties from the

menu, click on the Device Manager tab, double-click on Ports, then double-click

on the Communications Port your MTA128ST is connected to. In the ports
