[WT-support] Printer port and SO2R

[Franta Bendl]

Hi,

I checked the allocation of the control signals on LPT1 for SO2R and 
determined some ambivalence. The pin 4 is used for DVK (2) and Headphone 
control too. I believe that both signals can be in use at the same time. 
Would it be possible to handle "Headphone Control" like "Stereo RX audio" 
with possibility of choice between pin 4 and e.g. pin 10 or is there any 
other solution to avoid this conflict?
