41CL MMU Reset upon serial cable insert/remove

[rprosperi]

Another thread documented my issues troubleshooting getting my 41CL to do serial transfers. Thanks to lots of help and a specific tip from Michael Fehlhammer, I've been able to get this working.

Now, every time I insert or remove the serial cable on the 41CL end (plugged-in already on the PC side) the MMU is disabled. Note the configuration is preserved so I need only re-enable the MMU to continue.

A careful re-reading of the manual indeed says clearly that the 2.5mm plug should be inserted into the 41CL prior to connecting the DB9 end to the PC. I will test this tonite to see if it works w/o MMU reset, but I'm confidant it will work OK.

Have other 41CL users had this same experience?
