I have a problem using the TS-SER4 (Rev B) board connected to a TS7260
when I use setserial, I always get an error as shown below.
Board is set up with IRQ6 (IRQ2 and 4 jumpers), COM5 (jumpers COM1+4)
so that should be
address 0x11C003A8 8 bit IO
address 0x21C003A8 16 bit IO
I have tried these for addresses also
the device numbers for ttyS0 are (major,minor) = (4,68) chardev
Any suggestions ?
$ setserial /mnt/dev/ttyS0 uart 16550A port 0x3A8 irq 6 ^fourport
