RS232 for MIOS Studio

Is there anyway I can use the LTC module with rs232 of PC in MIOS studio?

My gameport is either not working, or giving big probs.

If you follow the instructions for the LTC module, you’ll get a new MIDI port available in MIOS Studio. It should just work like any other MIDI port. However, it might be cheaper/easier/more useful to just buy a USB to MIDI adapter.
