Dear Sir,
i m going to use NP5610-16 moxa device for multiport serial communication.
i m using fedora-core 6 o.s.
after installation it will detect serial ports as /dev/ttyr0,/dev/ttyr1...ttyr32.
there are total 32 com ports.
now i want to write application which monitor all serial ports and received data from particular serial ports simultaneously
after that it send data on particular port.
its ok i understand this concept.
but i confuse that what programming approach i have to use to monitor multiport serial ports.
i have to fire 32 diff threads for each port or what
