! Fixed samples to not query error value (since it RTEs if
the port is not open)
+ WIN_COMISVALID( <nPort> ) -> <l> added to check if port number is a valid one.
+ WIN_COMERRORCLEAR( <nPort> ) added to clear last error.
! WIN_COMERROR() changed to not clear the error on read.
+ WIN_COM():ERROR() method added to retrieve last error in numeric form.
* Samples changed to use :ERRORTEXT() to show errors.
; INCOMPATIBLE changes.
; DISCLAIMER: I'm not a user of this, so to raise your chances for
a fix, pls submit patches. I also couldn't spend huge
time to rethink the whole concept of these interfaces.
IOW: Contribute.
