What you need
USB to Serial cable (e.g. this one)
Null modem serial port adapter (e.g. this one)
A new configuration option usb_serial_baud_rate has been introduced. You’ll need to edit the mt32-pi configration file (mt32-pi.cfg). Replace the following line:
usb_serial_baud_rate = 31250
With this:
usb_serial_baud_rate = 38400
The PC serial port can’t run at the standard MIDI baud rate of 31250bps. Instead we tell our mt32-pi to use 38400bps – the closest “PC standard” baud rate.

Also, there's SoftMPU needed on the DOS PC.
It can route MPU-401 writes to PC serial port, but only for Real-Mode games I think.
Edited.
Edit: I tried to figure out which chip the "Sabrent CB-DB9P" cable uses.
It might be a Prolific chip, maybe the good old PL2303?
Other possibility is the FTDI FT232RL? Or CH340G?
I'm exactly not sure. Maybe the mt32-pi needs a specific USB serial chip?

Edit:
if i take a compatible card, can i use a soundblaster DB15 to midi cable (should have it around at home somewhere)?
I suppose, but I can't guarantee it.
Normally, things like Gameport, MPU-401 (UART) and OPL3 are not nearly as troublesome as Sound Blaster compatibility.
A PCI soundcard can do that, even under Windows XP in native mode (no SB Pro compatibility).
It's merely Sound Blaster standard that's tricky, since it uses ISA DMA.
The other peripherals merely need i/o ports in ISA address space, and some IRQs (the MPU is on IRQ 2/9).
