K56flex Modem Rules Of Thumb

 

 

What is required at the client-side?

For K56flex modem operation, the client-side modem must be operating with K56flex v1.0 software or higher. In many cases this will mean that the client-side modem will require a flash upgrade and, in a small base of modems, a hardware exchange may be necessary.

To determine if a client-modem is K56flex operational, a user can place the modem in the command mode and communicate directly with the modem using the AT command syntax. To enter AT commands you must attach your modem to a computer's serial port and enter commands directly from terminal emulation software such as Windows 95's HyperTerminal program. To use AT commands in terminal mode to verify software version, do the following:

  1. Start your data communications program.

  2. At the screen prompt type in ATi3 followed by a carriage return (or enter).

  3. Note the modems response on the computer screen.

  4. If the modem responds with V1.0-56K_DLS (or higher), a K56flex modem connection is possible.

  5. If the modem responds with an earlier version of software (such as V0.519-K56_DLS), please contact the modem vendor's web site for the latest firmware upgrade.


Which client modems are compatible with the PortMaster 3?
