Serial Port Interrupt Linux. you can reassign one of the interrupts to a serial device, and still happily use a parallel port. You will need the setserial program. If it's in use by another serial port you could try. check /proc/interrupts to see if the irq is currently in use by another process. in other words, when your serial port hardware generates interrupt, it's handled in kernel, and kernel generates. when the serial port receives a number of bytes (may be set to 1, 4, 8, or 14) into its fifo buffer, it signals the cpu to fetch. in this tutorial, we’ll walk through the process of configuring a serial port on a linux system, ensuring a. I have checked that the. #define my_irq 4 disable_irq (. the following sequence disables and then enables the interrupt for the com1 serial port: when configuring a serial port, we want to disable any special handling of output chars/bytes, so do the following: i am trying to set the interruption for a serial port in ubuntu (in program written in c), but it does not work.
