Serial Port Downloads to 41CL

I encountered a similar problem with the serial interface of one of my CLs;
the cause was simple:

From the CL manual:
14. Carefully plug the connector on the cable into the connector jack on the 41CL circuit
board with the “CP” label next to it. This is the programming connector for the CPLD.
The connector used is very fragile and was not really designed for multiple insertions,
so take your time, but make sure the plug is fully seated in the connector on the 41CL
circuit board.

In my case the plug was not fully seated, although this wasn't obvious at all.
I suggest you check that.

Thanks Michael, I wondered about this, but dismissed it since it seemed like wishful thinking. Since this is indeed a problem that someone has actually experienced, it's feasible that it's my trouble too. I honestly hope this is the cause, as that means I didn't break anything!

My current plan is to do the other testing Monte suggested first, but I may not have the patience and just open the case to check...

I'll let you know.

Thanks Michael!
