4
If 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.
4
Check for loose connections between the modem and the computer, the
telephone jack, and AC power.
4
You 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.
4
If 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.
2.7.5 The Modem Cannot Connect When Answering
4
Auto-answer may be disabled. Turn on auto-answer in your datacomm
program or send the command
ATS0=1 to your modem in terminal mode.
2.7.6 Slow File Transfer
4
You may have an older UART. For best throughput, install a 16550AFN
UART or a Multi-Tech ISI serial port card.
4
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.
4
If you are using a slow transfer protocol, such as Xmodem or Kermit, try
Zmodem or Ymodem/G instead.
4
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 clean line for
maximum speed.
4
Are you downloading a compressed file with MNP 5 hardware compres-
sion 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.
4
Try entering the
&V (View Parameters) command, making a screen print
of the diagnostics listing, and checking for parameters that may be
unacceptable.
