Modem problems
The modem dials the line but doesn’t connect, or cannot
maintain the connection.
You may be connected to a noisy telephone line. To check this,
connect an ordinary telephone to the telephone line and try placing
a phone call. If you hear an unusual amount of noise or static, try
connecting the modem to a different telephone line or connecting
at a later time.
There may be an incorrect setting in the communications software.
Refer to the communications software documentation to
customize the modem settings.
The modem won’t receive or transmit properly.
Make sure the RJ11 cable (the one that goes from the modem to
the telephone line) is firmly connected to the modem’s RJ11 jack
and the telephone line socket.
Check the serial port settings to make sure the hardware and
software are referring to the same COM port.
Check the communications parameters (baud rate, parity, data bits,
and stop bits) specified in the communications program.
The modem is on, configured properly, and still won’t
transmit or receive data.
Make sure the line has a dial tone. Connect a telephone handset to
the line to check this.
The other system may be busy or off line. Try making a test
transmission to someone else.
