how do i extend the range of registered serial interface?
hi all,
Im currently using kernel version 2.6.33.3 and i have recompiled. I have bought a serialboard(PCIe 7800) from addi-data and im not sure whether it is properly installed. I'm here to seek advise.
when i type in "cat/proctty/drivers", the listing contain a line:
...
serial /dev/ttyS 4 64-95 serial
...
when i type in "lspci",
03:00.0 System peripheral:ADDI-DATA GmbH Unknown Device 7023
03:00.1 Serial Controller:ADDI-DATA GmbH Unknown Device 7013
from my card distrubutor, 7013 means it is APCIe-7800. meaning my system identified the board correctly. why is there an "Unknown" word in the line?
when i type "dmesg", it only shows i have 4 ports,
...
Serial: 8250/16550 driver, 4 ports, IRQ sharing enabled
...
and i dun have the identification of the PCI slot in which the board is plugged from these "dmesg" command which are usually type MMIO.
Regards.

It means that there is no driver installed for this board, even though lspci's scan sees it. The /dev/ttySN entries are for the recognized serial ports. The line you find in /proc/tty/drivers basically means that the default serial port driver for 8250/16550 UARTS. I assume that you only find the 4 default serial ports in /dev - /dev/ttyS0 thru /dev/ttyS3?
Sometimes, real fast is almost as good as real time.
