I am using Windows 95/98/ME. How can I determine if my Digi ports are functioning? I am using Windows 95/98/ME. How can I determine if my Digi ports are functioning?
If you have a modem and the Digi ports are rs232,
to verify that the Digi ports are functioning, go to the URL below and download TTY.exe to test the ports:
Run the executable and choose Settings. Select the com port to which you have your modem connected.
Configure the communications settings to match the modem and choose OK. Then choose Action, Connect.
You should be at a modem command prompt (you will see a blinking cursor). Try typing AT and hit return to see if the modem will respond with an OK. This will show that the data was sent to the modem and a response was received back from the modem.
If you do not have a modem, or if you have rs422 Digi ports, put the Digi loopback connector on the port you wish to test. Obtain and run the TTY.exe as above.
At TTY's session prompt, try typing on the keyboard. The characters that you type within the terminal session should be echoed back to the console. If you can see what you are typing, this shows that data is being both transmitted and received on the port.
NOTE: If you have rs232 Digi ports, it is possible to start two instances of TTY and test the ports by connecting them with a standard "NULL MODEM" cable. Set each TTY session's parameters to the same baud rate, parity, and stop bits. Try typing some characters in the active window. If you see characters appearing in the opposite window, then the ports are communicating.
