To test the connection of the POS-server to POS-terminals, use the HyperTerminal utility. This program is free and not included in Windows OS.

See the official HyperTerminal documentations for its usage details.

To test the POS-terminal connection, do the following:

  1. Launch HyperTerminal on the POS-server. The utility interface window will open, and the Connection description dialog box will appear.
  2. In the Name field, enter a meaningful name for the connection, then click OK.

  3. The Connection window opens. Select a network type in the Connect using drop-down list.

     Select the connection type according to the POS-server to POS-terminal connection.

  4. If TCP/IP (Winsock) interface type is selected, then select the local port number in the Port field and click OK.

    An information box will appear with the following message: Unable to connect to port 2555. Click OK to close this box, then click Wait for a call in the Call menu.

  5. If the COM interface type is selected, click OK. In the Properties: COM window that opens enter the required parameters and click OK.

    The COM connection settings should meet the POS-terminal data transfer settings.
  6. Start sending data from the POS-terminal to the POS-server
  7. In case of successful connection, the data will be displayed in the HyperTerminal window .
