Delphi 7 XP prof.
I'm using the free Tcomport component for Delphi. Although I do not usually have problems, there is one bugbear that I cant seem to solve.
If you have a couple of USB serial converters connected to the PC, sometimes there is a problem with port initialisation.
Is there a simple way to find out which Comport belongs to which external USB-serial device?
How does the allocation of these devices occur?
What exactly is the meaning of Purgecomm function failed?
