otazka znie inac
ako by mohli dva spustene perlovske programi navzajom komunikovat
posielat si medzi sebou data
napr: (perl TK program) - (perl demon - serial & parallel port)

sockety - ci uz inet alebo unix

alebo filesystemove FIFO rury, alebo UNIX System V komunikacne mechanizmy.

parada ze niekto mi odpoveda
googlil som nieco okolo socket ale vecsinou je to na sietove prenasanie
viem ze perl modulov je vela ale neviem ich pouzivat
a angl. verzie manualov mi velmi nejdu
uz pol roka sa ucim a skusam perl tk a je toho hrozne mnozstvo

nepoznate nejake forum kde o takychto veciach (perl tk programs) viac pisu ?

0000010100063540020763990165500202445419024475570244919002449431024508370245340202454755

socket je genericka ficura na medziprocesovu komunikaciu
netusim preco by mal byt viac na sietovu komunikaciu ako na komunikaciu cez cokolvek ine
o perl tk forum v ne-anglictine nepoznam, ale snad toto je vhodne miesto

a este nieco
nechapem preco by modul na komunikaciu parportom mal byt obmedzeny na roota
si si isty, ze ma subor zariadenia dobre prava?
ak hej, skus priblizit ze co sa deje zle, ked to spustis ako normalny user

a ak to spustim ako root tak

funguje to aj napriek tomuto warningu

pouzivam Active perl
Device::ParallelPort linux.pm som priamo v nom pozeral aje tam ze
=head2 Special Requirements
You must be root to run this code.
linux uz spoznavam 5rokov o opravneniach spustania uz viem
tak som sa rozhodol ze pri starte linuxu spustim demon v ktorom bude serial aj Parallel
moj program bude komunikovat s demonom len neviem ako medzi nimi posielat data
demon mi aj vyhovuje lebo parallelnym portom idem ovladat motory krote sa spustaju
jednotlivymi bitmi - set_bit(1, 1); sleep $cas; set_bit(1, 0);
takze sleep nebude brzdit perl tk program
cez serial port prichadzaju namerane data kazdu sekundu a tie potrebujem citat
este posledna .. potrebujem nieco ako (prerusenie) v perl tk programe
ze ak sa naplnia data zo serial portu .. tak nieco ... (ukladanie do suboru)
