serial port configuration problem
I have a minilinux that I being working on, the problem now is that the serial ports doesn’t seem to work (I have 4 serial ports).They don’t write or read.
I run the command setserial –g /dev/ttySx and it says that his IRQ are 3 or 4 (3 for ttyS0 and ttyS2 , 4 for ttyS1 and ttyS4)…but when I run the command: dmesg | grep ttyS the IRQ’s are 0 for ALL my serial ports… could be this the reason why my serial ports aren’t working right??? And if it is how can I solve the problem???
Hope someone could help me.
