In an older post albertr mentioned he got nothing valid out of the serial lines on his C1000.
No, I never said that. In fact, I posted many times on this (and other forum) that serial UART lines are available on Sharp I/O port on 1000/3x00 Zaurii. They are logical 3V TTL levels, so need RS232 tranceiver. In fact, I'm using it on my C1000 with Sharp serial cable quite often.
There's no JTAG lines on Sharp I/O port on 1000/3x00 AFAIK.

Hi albertr,
i'd really like to apologize for my statement .
I didn't remember the exact post as i wrote these lines and i thought it was you who once mentioned kind a thing. Blame on me
Never ever i'll write something down again, if i do not exactly know where i got it from.
At least i wanted to point out that there were many different opinions about the serial stuff and I/O connector.
But it seemed that i was the only one confused !
Perhaps this is a good moment for me to send a personally "thank you, albertr".
It amazing what you have done so far and what information you put down into this forum!
Let me go back to the topics.
guylhem may be right.
I think there could be some kind of gate logic inside C1000/3x00, which is activated with pin 13 and maps the JTAG lines to the pins 5,6,7 and 14 on the I/O connector.
I will do some investigation. Unfortunately i got no schematic of the device.
