I had a minute to test it and it worked fine for me.
Are you using a USB to Serial adapter? If so, go to Control Panel, Device Manager, Ports and verify which port the USB to serial was assigned. Enter that into the program. If that still doesn't work, try other Baud rates.
Just played with two settings. If you enter an "invalid" COM port you get the message "open COM error". If you enter the wrong baud rate you get the message you had in your post so I am assuming you need to try the other baud rates. I would try 38400, then 57600 and finally 115200 to see if one of those work. If not try lowering.
Also, being an older Toughbook, you may have to set the port speeds on your computer. Control panel, device manager, ports, right click on the port and select properties. Under Port settings, change the speed to 19200
