Hondata

My laptop only has one serial port. It's labeled port 5. The hondadta s200 software only allows for ports 1-4. What do i do?

Go into the device manager and change the port number allocated to the serial port to com1-com4. Sometimes you have to remove ports assigned to internal modems, set the port for the serial port, then let windows reinstall the drivers for the internal modem(s).
