Hi all
According to the manual, you can use one LPT port for CW paddle
input or radio switching output but not both. It would seem to
me that this is because there is not always voltage on pin 14
for pullup.
My question is - can you get around this if you have another
source of + 5 volts for pullup on pins 12 & 13?
Thanks
