I am making LPT / CW interface cables for the W1QK VHF contest group.
Here's the problem - the paddle input does not work on his computers (P100,
DOS6.2)- the Function keys will generate CW, though. The paddle input works
fine on my laptop (486, WIN95). All computers are running a 10+ version of
CT for DOS. I have pull-up resistors - OC voltage measures ~5V on both
computers.
Questions- are all LPT ports created equal? Is this is HW or SW or OS
related? Has anyone encountered this issue? Any suggestions on solving this
mystery?
TIA
Bob W0BR/1
