Tak jsem zjistil, že to možné je, ale nevím jak to připojit, je u toho nějaký návod:

1.Connect two serial ports with a null modem cable.
2.On your development workstation, install ActiveSync.
3.From the Target menu, choose Configure Remote Connection, and then choose the Services tab.
4.From the Download box, choose Emulator, and then choose Configure.
5.If KITL is built into your OS image, from the Serial Port 2 box choose COM1 or COM2, and then from the Serial Port 1 box choose None.
- or -

If KITL is not built into your OS image, from the Serial Port 1 box choose COM1 or COM2, and then from the Serial Port 2 box choose None.

6.Choose OK, and then choose OK again.
7.Configure ActiveSync to connect to the serial port — either COM1 or COM2 — that you did not assign to the Emulator.
