Hello,

this is my first post to this forum. I hope so far, it is ok to you. I
try to connect my pascal code to serial ports like /dev/ttyS0. If I
use indeed /dev/ttyS0 ... S3, it works fine. But it seems, fpc doesn't
understand serial ports like /dev/ttyS4 or /dev/ttyUSB0, and I cannot
figure out, where the problem is. I intend to use the unit serial and
hope so far to find someone, who knows, what can be done to get the
code running as expected.

Best wishes, Holger
