[TRLog] Parallel port keying
Fri, 10 Mar 2000 20:39:41 GMT
TR works fine for me using LPT1 to key Radio 1 and LPT3 to key
This weekend I wanted to use SuperDuper to run BERU which is
supported by that prog. ( RSGB contests its raison d'etre)
However it would not key from LPT1 and LPT3 is not supported.
Paul/EI5DI opines that this is because my LPT ports are using
non standard addresses as below,
LPT1 03BC No IRQ Radio 1 key port
LPT2 0378 IRQ7 Printer port
LPT3 0278 No IRQ Radio 2 key port
whereas SD only supports addresses 0278 and 0378.
The puzzle therefore is why TR manages to use LPT1 with this non
standard address ( 03BC).
Can anyone explain this to me. Is this another piece of magic in
