I thought update was the default , its works fine normally !
I will  try though !

On my script , open works and write , hangs pc on read i think !
On Sarah's script it hangs pc on Open !

I do have a timeout in reality , makes no difference !!!

You bet ! no ctrl break , no task manager kill process , no nothing !!!
Only Reboot for my script and Sarah's !!

Well , that's why i use Rev , so i don't have to program in C any more.
What I mean in "C" based programs are programs like Hyperterminal and other
third party
Serial Port Monitors.
These all work perfect with the Virtual Device/Driver , so as far as
pretending to be a Com Port
it's okay on all programs except REV !!

I think it's a Rev issue that needs addressing URGENTLY !!

Best Regards
Camm
