For 2021 - online Python 3 training - see ((here)).

Our plans were to retire in summer 2020 and see the world, but Coronavirus has lead us into a lot of lockdown programming in Python 3 and PHP 7.
We can now offer tailored online training - small groups, real tutors - works really well for groups of 4 to 14 delegates. Anywhere in the world; course language English.

Please ask about private 'maintenance' training for Python 2, Tcl, Perl, PHP, Lua, etc.
Serial port 'pretends' to work!

Posted by rpmorrow (rpmorrow), 24 October 2007

I have written a program which uses a serial port on a Windows PC. It used to send an recieve fine, but now it won't. I haven't changed the comms code and it throws no exeptions so it's pretty strange.

The only clue I have is that the file handle given by [open com4: r+] is diferent.
When working it shows as "filee145d0"
When not is shows as "filee64048"

When it's not working, the command is within a procedure, but no errors are shown and nothing shows with the -laserror thing either.

Does anyone know what would cause this?

Cheers, Rich
