Depends on what you are connecting the serial port too and how the software works.
I have countless problems with getting MYOB Retail Manager / Retail Basic and USB to Serial Adaptors.
I got a client of mind that has commented how these adpators get in the way when he's programing alarm systems.
With out getting to technical about it, most software seems to be happy with working on Coms 1,2,3,4. However when USB Serial Port Adaptors have this habit some time picking random com port numbers out of the air. Especially when sone one disconnects and reconnects the USB to Serial port while the computer it still on. Main reason is that Windows things that there is a new com port being added.
