How To: Use KERMIT to test your digitizer



The KERMIT program is used to test how well the digitizer and the PC are communicating outside of PC ARC/INFO.

KERMIT is a public domain terminal-emulation package included with the PC ARC/INFO STARTER KIT. You can also use any other terminal-emulation package that allows you to set serial communication parameters.


To test with KERMIT, do the following:

1. Open a Command Prompt (DOS) window.

2. Type KERMIT at the DOS prompt.

3. At KERMIT prompt, type the following:

Kermit-IBMpc> SET PORT x <-------- where x is the PORT number
Kermit-IBMpc> SET BAUD 9600

4. Randomly press buttons on the digitizer's puck and see what appears on the monitor. This data will tell you what mode the digitizer is using to communicate:

- ASCII (or MM format): letters and numbers only, e.g. AP32454537891

- BINARY (or UIOF format): letters, numbers, and other special characters, e.g. %!#@4$}X

If no data appears on the screen, your digitizer is not communicating with your PC, in which case you can do the following:

1. Make sure the cabling between the digitizer and your PC is correct, as per the digitizer manufacturer's documentation for cabling requirements.

2. Make sure you have specified the right PORT.

3. To make sure the PORT is working correctly, attach another serial device
to test this.

4. Make sure the digitizer is working properly: it is ON, and the puck is working properly.

If after this, there is no data communication between your PC and the digitizer, it may be advisable to get the Digitizer company to help you set up the digitizer.

If you tested the digitizer using the Windows driver, you should uninstall the Windows digitizer driver, since PC ARC/INFO does not use the windows digitizer drivers.

To exit KERMIT, simply type Quit at the prompt.
