Subject: Re: [fpc-pascal] How to detect serial/usb-serial ports.
For which operating system?
I'd expect (recent versions of) those to only create devices that were
known to exist. I detect what's available by looking for up to 12
/dev/ttyS*, 8 /dev/ttyUSB* and 4 /dev/ttyI*, then later checking that
they can actually be opened (bearing in mind that this might glitch a
control line).
It's worth noting that a few weeks ago I was updating the standard
serial.pp unit and noticed that Solaris designated serial ports as
/dev/ttya and /dev/ttyb.
Windows of course is \COM1, or strictly \\.\COM1 etc.; I note Fabio's
test but in the past have used the registry to find e.g. named ports
simulated by an AVR box.
