The Modem Does Not Respond to

Commands

• Make sure you are in terminal mode in your data

communications program, then type AT and press ENTER.

If you get an

response, your connections are good and

the problem likely is in the connection description in your

communications software.

• Try resetting your modem by sending it an

ATZ

AT&F

command in terminal mode. If you are using legacy

software— software designed for an older operating

system—make sure the initialization string includes

the first command, to cancel any “leftover” commands that

could interfere with the modem’s operation.

• If you don’t get an

, 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 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, its 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 Modems

Properties sheet. (Select Start, Settings, Control Panel,

Modems, Diagnostics.)

• Another expansion card, such as a bus mouse or sound

card, might be using the same COM port, memory address,

or interrupt request (IRQ) as your modem. On the Windows

95 desktop, right-click on My Computer, select Properties,

Device Manager, and Ports, then double-click on the
