[1000mp] FT1000mp serial port communication

[Rob Murray]

I had a problem communicating between my laptop and my Mark V serial port. I
checked everything - the laptop worked fine with everything else, the cables
were fine, all the pini outs were right, etcetra. Turns out these radios
require an unusually high serial signal input level, and my laptop, although
it works fine with everything else, just wasn't shouting loud enough to get
any response from the rig. I switched to an old tower computer and the rig
talks to it fine, never a problem.

Perhaps your home brew serial port is just 'on the edge' of your rig's
signal level requirement. If it is, the only fix is a different (higher
output) serial port.

I remember muttering what about the RS232 standard, and being advised that
it is often referred to as the RS232 non-standard...

Just a thought
