Modem problems
This section lists common modem problems:
The modem will not receive or transmit properly.
Make sure the cable from the modem to the telephone line is
firmly connected to the computer's modem port and the telephone
line jack.
Check the port settings to make sure the hardware and software
are referring to the same COM port.
Check the communications parameters (baud rate, parity, data
length and stop bits) specified in the communications program. It
should be set up to transmit at 300, 1200, 2400, 4800, 9600,
14400, 28800, 33600 bps (bits per second) or higher. Refer to the
program's documentation and the modem manual for information
on how to change these settings.
TECHNICAL NOTE: Disable Call Waiting before you connect
through the modem. Call Waiting interrupts data
transmission.
The modem is on, set up properly and still will not 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.
