last sunday I tried to connect a laptop to the instrumentation of a
boat with a B&G Hydra 2000 system.
I downloaded a paper from b&g site:
http://www.bandg.com/pdfs/FAQs/faq007.pdf
where they use a cable named 135-0a-160
since i don't have such cable, i cut a serial cable and connected the
wires (according to the pins specified in the table) to the nmea
processor i started several serial port sniffers (also one written by
me), but, of course, it didn't work
i tried to use only pins gnd, rx and tx, tried also to swap rx and
tx, but still nothing
tried also on several different ports of the processor
my port sniffer sometimes reads strange characters, so I thougth that
the cable referenced in the document may have some electronics
inside, but I couldn't find any useful info about that
anyone can help me out on this?
thanks

As suggested by Wout B, connect together pins 4 & 6, and pins 7 & 8 on the
RS232 plug. (You don't have to take the plug apart if its moulded, trace the
wires and split the cable, then join the wires using a small nylon
connector.) Use a 35mm film canister with holes dtrilled in the lid and
bottom to conceal the joins (enclose the nylon connector within the
canister.)

If flow-control is needed, this will get round the problem.
