How to communicate other device with serial communication

Any idea to create the code for serial communication RS-232 by interrupt method.[/img][/list][/list][/code]

The RS-232 driver supplied with QNX 6.3 uses interrupts. You only need to open /dev/ser1 or /dev/ser2 and then call read() and write().

use select() or ionotify() + MsgReceive() / MsgReceivePulse()

readcond() is also very useful
