Focus on getting an interface working, whether it's the 1 or 2
transistor
circuit or a MAX232 IC version, probably 90+% of the time the 1
transistor
circuit will work, while the IC version is just about 100% guaranteed to
work. Try another vehicle, another laptop, move a desktop PC out to the
garage temporarily, enlist the help of a buddy, 'scope signals, make
sure
the serial port is working (not disabled in BIOS), laptop battery fully
charged, etc., etc. Get *something* working, troubleshoot from there...

I note from the WinALDL revision list that there was a change for CLCC
in V1.05b, so try a version before that one also, your laptop may like
an earlier one for some reason.
