[luau] Serial with Perl

[whenever]

Anyone does serial programming here? I need to send commands and recieve 
results from a serial port that has a VT`100 emulation on the other end.  I 
don't want to use expect, perl would be great/easier for me, but I haven't 
done serial code before, can someone give me an example? I have looked at 
Device::SerialPort, IO:Tty, Comm.pl(last choice on this one or FileHandler) 
and POSIX::termios, I am still a little lost there.

Thanks
