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, select Properties from the menu, click on the Device Manager tab, double-click on Ports, then double-click on the 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.
