8 Solving Problems

 

 

The Modem Cannot Connect When Answering

ÖThe default DTR Control command (&D2) inhibits autoanswer. To enable autoanswer, change DTR Control to &D0, and make sure &Q0, &Q5, or &Q6 is also set. For more information, see the &D command in Chapter 4. For information on changing the modem’s default configuration, see “Step 6: Install and Configure Your Software” in Chapter 2.

ÖAutoanswer might be disabled. Turn on autoanswer in your communications 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

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

ÖIs 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.

ÖAre 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.

ÖDoes your Internet service provider (ISP) use the same 56K protocol as your modem? The default setting of your modem is to connect using either the V.92 or the V.90 protocol, depending on which one the ISP’s modem is using. If your ISP uses the V.90 protocol, the maximum speed you will be able to upload at is 33,600 bps. Check with your ISP to see which protocols it supports.

ÖAre you trying to send a file to another client modem? If so, then your maximum possible connect speed is 33,600 bps. You can upload at speeds up to 48,000 bps only when connected to an ISP that supports the V.92 protocol.

ÖTry entering the I11 command in online mode or the &V command in command mode to display information about the last connection, making a screen print of the connection statistics, and checking for parameters that might be unacceptable.

Data Is Being Lost

ÖIf you are using data compression and a high speed serial port, set the serial port baud rate to two to six times the data rate.

ÖMake sure the flow control method you selected in software matches the method selected in the modem. If you are using the modem with a Macintosh, you might have the wrong cable for hardware flow control.

ÖTry entering the I11 command in online mode or the &V command in command mode to display information about the last connection, making a screen print of the connection statistics, and checking for parameters that might be unacceptable.
