HP41CL Serial Com Port Failure

[Neve]

Hi Sylvain,

I understand you’re busy, don’t worry. And yes, I finally hit the CTRL C keys.

I would understand if one CL had a defective serial port…. But both at the same time? This is highly unlikely, although not impossible.
It could be the serial cable…. I’ll try to use it with something else and see how it goes.

The only thing I see on the CL side is « COMM », and then « TIME ERR ». At that point I just hit CTRL C.
