Advanced Modem Settings

Hang Up Time

If you need the modem to hang up right away after authorization, set Line Delay in CreditLine Authorization Parameters Dialog to 1 to 2. Make sure to check Apply To All. This will hang up the modem right away

Custom Modems

If you want to use a modem that is not supported by us, you will need a custom init string. The basic purpose of the init string is to turn off the compression, error correction, and high speed handshake off to speed up the dialing and ensure the connection to the host. The hosts do not support any of the above modern features. To make a modem work with the credit card hosts, go over the user's manual to make sure the following:

  • Always connect at 1200 baud rate.
  • No compression.
  • No error correction.
  • No buffering.
  • Do not use ATZ in the init string.

USB and Internal Modems

We do not recommend the use of internal or you USB modems. Internal modems cannot be reset without shutting down the server and USB modems have proven to be less reliable in the demanding Point Of Sale invironment. For computers without USB ports use a USB to Serial Port converter and a Serial Port modem.
