LINUX Installation This installation guide describes the procedures to install NetMos Technology Nm9735CV, Nm9745CV, Nm9835CV, Nm9845CV PCI serial ports in Linux platform. Linux Platform l Operating System : RedHat, SuSe l Terminal Emulation AP : minicom l Internet Dialer : Kppp Installation Serial Ports Find the available serial ports Since Linux only support 4 serial ports (ttyS0, ttyS1, ttyS2, ttyS3) under the default condition. Most likely, ttyS0 & ttyS1 are supported by mother board's built-in serial controllers and ttyS2 & ttyS3 are free for additional I/O card. Serial ports could be checked by the following commands. setserial /dev/ttyS0 -a (COM-1) setserial /dev/ttyS1 -a (COM-2) setserial /dev/ttyS2 -a (COM-3) setserial /dev/ttyS3 -a (COM-4) If COM-1 is used by mouse, the response is similar to /dev/ttyS0 : Device or resource busy If the COM-1 does not attach any device, the response is similar to /dev/ttyS0, Line 0, UART: 16550A, Port: 0x3f8, irq: 4 Baud_base: 115200, clos_delay: 50, divisor: 0 closing_wait: 3000, closing_wait2: infinite Flags: spd_normal skip_test In case ttyS2 (COM-3) is free, the response for command setserial /dev/ttyS2 -a is shown below. /dev/ttyS2, Line 2, UART: unknown, Port: 0x3e8, irq: 4 Baud_base: 115200, clos_delay: 50, divisor: 0 closing_wait: 3000, closing_wait2: infinite Flags: spd_normal skip_test Find the PCI card resource ( I/O port address & IRQ) for the serial ports Enter the command more /proc/pci The response is similar to the following Bus 0, Device 11, function 0: Serial controller : Unknown vendor Unknown device (rev 01).

Especially, the NetMos parts always shows Vendor id=9710, Device id=9735 Device id=9745 Device id=9835 Device id=9845 Configure the parameters for ttyS2 or ttyS3 Enter (if ttyS2 or ttyS3 are free) setserial /dev/ttyS2 port 0xc000 UART 16550A irq 11 Baud_base 115200 setserial /dev/ttyS3 port 0xc008 UART 16550A irq 11 Baud_base 115200 Check the setting for ttyS2 or ttyS3 Type setserial /dev/ttyS2 -a /dev/ttyS2, Line 2, UART: 16550A, Port: 0xc000, irq: 11 Baud_base: 115200, clos_delay: 50, divisor: 0 closing_wait: 3000, closing_wait2: infinite Flags: spd_normal skip_test The ttyS2 or ttyS3 are ready for application Installation Parallel Ports Installation Guide for PCI Parallel Ports This installation guide describes the procedure to install the Nm9705,Nm9735CV, Nm9805CV, Nm9715CV, Nm9835CV, Nm9755CV PCI parallel ports in Linux platform. Linux kernel provide a 'parport' code to support parallel port (/dev/lp0, /dev/lp1, /dev/lp2). This code provides the ability to share one port between multiple devices. And it is loadable when kernel is running. The 'parport' code is split into two parts : generic (which deals with port sharing) and architecture-dependent eg. X86, SPARC. (which deals with actually using the port). Thus, please take the following steps to install 'parport' module! Check the on-board parallel port's hardware resources Most likely each motherboard has a built-in parallel port. And its hardware resources are settable with BIOS utility. Enter the command more /proc/pci The response is similar to the following Bus 0, Device 11, function 0: Serial controller : Unknown vendor Unknown device (rev 01). Vendor id=9710, Device id=9705 Device id=9735 Device id=9805 Device id=9815 Device id=9835 Device id=9855 Medium devsel. Fast back-to-back capable.

Check the attached printer device [optional] Once the architecture-dependent part of the paraport code is loaded into the kernel. You could enter the following command insmod parport_probe.o To check any attached devices and log a message similar to parport0: Printer, epson Then /dev/lp0, /dev/lp1 and /dev/lp2 are ready for service
