In terms of Serial Ports what does COM actually stand for. I can't find any reference to it.
(To be clear I am not talking about Component Object Model but the Hardware Interface used in Windows Environments)
I assume it is an acronym as it is always capitalised?
It stands for communications i believe - since parallel ports were lpt (or line printer ports) and serial ports were used for communications.
Interestingly I haven't found any reference that confirms this so far however - this is the closest i can find to a reference, but it seems to be taken for granted in windows and dos. There's no acronym or acronym for COM as far as i can tell
(Interestingly in linux, they are called tty - which refers to a teletype machine)
