Multi-Tech Systems MT5634ZPX-PCI-V92 manual There Are Garbage Characters on the Monitor

Page 58
At speeds above 2400 bps, the remote modem might not use the same transmis- sion or error correction standards as your modem. Try connecting at a slower speed or disabling error correction. (With no error correction, however, line noise can cause garbage characters.)
Your computer and the remote computer might be set to different word lengths, stop bits, or parities. If you have connected at 8-N-1, try changing to 7-E-1, or vice-versa, using your communication software.

There Are Garbage Characters on the Monitor

"You might be experiencing line noise. Enable error correction, if it is disabled, or "hang up and call again; you might get a better connection the second time.

Enter the I11 command in online mode or the &V command in command mode "to display information about the last connection. Then make a screen print of the

connection statistics, and look for unacceptable parameters.

The Modem Doesn’t Work with Caller ID

Caller ID information is transmitted between the first and second rings, so if "autoanswer is turned off (S0=0) or if the modem is set to answer after only one

ring (S0=1), the modem will not receive Caller ID information. Check your ini- tialization string, and if necessary change it to set the modem to answer after the second ring (S0=2).

Make sure that you have Caller ID service from your telephone company.

Fax and Data"Software Can’t Run at the Same Time

Communication devices can be accessed by only one application at a time. Under "DOS or Windows 3.1x, you can run either your fax software or your data com-

munications software, but not both at the same time, unless you have a special communication device management application. In Windows 95 and higher, you can have data and fax communication applications open at the same time, but they cannot use the same modem at the same time.

The Voice Functions Don’t Work

There are several tests that you can perform to verify the voice circuits of the Multi- ModemZPX. First, make sure all connecting cables—telephone, microphone, and speaker—are undamaged and firmly connected to the correct jacks. Then retry whatever action was not working. If the problem persists, try the voice mail test; if that doesn’t work, and if you have a microphone and speaker connected to the MultiModemZPX, try the loopback and speakerphone tests, which do not require special software.
