I am having some trouble with a custom serial port setup on my machine. Specifically, I have a mouse on cua0(com1), modem on cua1(com2), and a Sparc IPC connected to cua3(com4) for use as the console. The setup is as follows:
TTY Port IRQ UART cua0 0x3f8 4 16550A cua1 0x2f8 3 16550A cua3 0x2e8 5 16550A
The problem is that new characters arriving on cua3 are not generating any interrupts as can be seen in /proc/interrupts:
I have been setting the parameters on this port using setserial for quite a while and I can't seem to get it to work. I also recompiled minicom suspecting that something might have broke between 1.2.13 and now, but it didn't have any effect.
It sounds like you didn't set the dip switch settings on your COM4 board to actually use IRQ 5. You realize that you have to change more than just the settiongs in rc.serial and setserial, right? You actually have to configure the hardware to use IRQ 5.....
