Here's what to do:
1. Make sure all communication parameters (baud rate,
data, stop, and parity bits) are properly configured and
identical on both sides. Also make sure the hardware
control flow (RTS/CTS) is enabled in both the modem
and the communications software.
2. Press the Enter key several times. The remote system
may be waiting to receive your data before it begins.
3. Make sure the correct terminal emulation mode is used
in the software. Refer to the information that came with
the software.
1. Make sure the Call Waiting feature is turned off.
2. Make sure the RTS/CTS hardware flow control is
enabled (do not use XON/XOFF software flow control).
3. Make sure the data speed is not faster than your
computer's capability.
