Use your communications software to verify that
the character format (data bits, parity, and stop
bits) is set to the same value in both modems.
Refer to page 3-4 for supported formats.
Verify that you are using the same method of flow
control for both the modem and the computer
(RTS/CTS or XON/XOFF).
If using XON/XOFF flow control, verify that the
modem's parity matches the computer's parity.
Refer to page 3-4 for information on supported
data character formats.
Your modem is not using error control and the
other modem is using error control. The garbage
characters are part of the error control
handshaking sequence.
Verify that you are using the same method of flow
control for both the modem and the computer
(RTS/CTS or XON/XOFF).
Make sure that the &D2 command is set.
Make sure that the &C1 command is set so that
when the CD signal turns Off, the modem hangs
up.
Action

configured for modem operation.
