To change it in Windows 95 HyperTerminal, select Call, Connect from the menu bar, click Dialing Properties, check This Location has Call Waiting, and select the correct code for your phone

service.

4If you have extension phones on the same line as your modem, you or someone else can interrupt the connection by picking up another phone. If this is a frequent problem, disconnect the extension phones before using the modem, or install another phone line especially for the modem.

4Check for loose connections between the modem and the computer, the telephone jack, and AC power.

4You may have had a poor connection because of line conditions or the problem may have originated on the other end of the line. Try again.

4If you were online with a BBS, it may have hung up on you because of lack of activity on your part or because you exceeded your time limit for the day. Try again.

The Modem Cannot Connect When Answering

4Auto-answer may be disabled. Turn on auto-answer in your datacomm program or send the command ATS0=1 to your modem in terminal mode.

Slow File Transfer

4You may have an older UART. For best throughput, install a 16550AFN UART or a Multi-Tech ISI serial port card.

4If 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.

4If you are using a slow transfer protocol, such as Xmodem or Kermit, try Zmodem or Ymodem/G instead.

4Is 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 clean line for maximum speed.

4Are you downloading a compressed file with MNP 5 hardware compression 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 with it disabled.

4Try entering the &V (View Parameters) command, making a screen print of the diagnostics listing, and checking for parameters that may be unacceptable.
