4The Modem Cannot Connect When Answering

Autoanswer might be disabled. Turn on autoanswer in your data- comm program or send the command ATS0=1 (ATS0=2 if you have Caller ID service) to your modem in terminal mode.

File Transfer Is Slower Than It Should Be

You might have an older UART. For best throughput, install a 16550AFN UART or a Multi-Tech ISI serial port card. See the “Quick Start” chapter for information on how to identify your UART.

If you are running under Windows 3.1 and have a 16550AFN UART, you must replace the Windows serial driver, COMM.DRV, to take full advantage of the UART’s speed.

If you are using a slow transfer protocol, such as Xmodem or Kermit, try Zmodem or Ymodem/G instead.

Is your line noisy? If there is static on your line, the modem has to resend many blocks of data to insure accuracy. You must have a

4clean line for maximum speed.

Are you downloading a compressed file with MNP 5 hardware com- pression enabled? Since hardware data compression cannot compress a file already compressed by an archiving program, the transfer can be marginally slower with data compression enabled than

4with it disabled.

Try entering the I11 ommand in online mode to display diagnostic information, making a screen print of the diagnostics listing, and checking for parameters that might be unacceptable (number of re- trains, round trip delay, etc.).
