Note: *70 is used only in the United States.

•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 for the modem only.

•Check for loose connections between the modem and the telephone jack.

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

•If you were online with a BBS or commercial online service, it may have hung up 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

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

File transfer appears slower than it should

•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 clean line for maximum speed.

•Are 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.
