I am having issues with SoftMPU outputting data to my MT32-Pi, and although I once got output to work using the DOSMID player and the direct to COM1 switch, I couldn't replicate that last night so I got to thinking about trying a different serial card. I disabled my current serial port via jumper on my VLB multi I/O card, but my PC isn't detecting my new card.

I am thinking this is jumper related, but I cannot find any trace of jumper settings for this card anywhere on the internet. Any assistance is greatly appreciated.
