I will be doing (4) as soon as I've found the time to make up a TTL to
RS232 board.
I suggest trying it without anything fancy.
All the GPS toys I've tried work fine without any conversion gear.
The normal TTL to RS-232 chips include an inverter. That will break things
unless you add

Well, I plugged my Oncore UT+ into my PC and it didn't work

Bruce, Chris, thanks for the confirmation.
I'll go back to the idea of using the MAX232 equivalent as originally
planned.

It has an ordinary octal
