Modem experiences errors while communicating

with a remote modem.

1. Make sure the DTE speed is the same as the modem connec-
tion speed when in Direct Mode (\N1 command in effect).
2. Make sure the remote system and your modem use the same
communication parameters (i.e., baud rate, data bit length,
parity, and stop bit).
3. Make sure RTS/CTS hardware flow control is enabled and
XON/XOFF software flow control is disabled in the commu-
nication software.
4. Make sure the data speed is not faster than your computer's
capability. Most IBM compatibles are capable of 19,200 bps
under DOS and Windows. Operating at higher speeds under
Windows requires a faster CPU (386/486 or better).

Modem experiences bursts of errors or suddenly

disconnects while communicating with a remote

modem.

1. Make sure Call Waiting is turned off.
2. Make sure the phone line does not exhibit excess noise.

Modem exhibits poor voice record or playback.

1. Make sure the correct modem type is selected in the Voice/
FAX software. Use “Cirrus Logic” or similar selection. Do
not select “Rockwell or Rockwell ICS” configuration.
