I did already create a script "listserial" that does the extraction:
(long line split by newsreader)

-----------------------------
#!/bin/bash
SERLIST=$(ls -l /sys/class/tty/*/device/driver | grep -v
"platform/drivers/serial8250" | awk '{print $9}' | awk -F'/' '{print "/dev/"
$5}')
echo $SERLIST
-----------------------------

This successfully lists the available serial ports by their device name, which
can be used to open the port using the built-in serial unit functionality.

Of course I *could* call the script from the program but I wanted it all be
within the FPC program itself...

But it can be done by calling the standalone script file of course...
