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

From the  /proc/pci file, it is possible to find the PCI card's I/O port address and IRQ. Especially, the NetMos parts always shows

			Vendor id=9710, Device id=9735
					Device id=9745
					Device id=9820
					Device id=9825
					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 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

Install 'parport' module

To load the generic 'parport' code

Type 			insmod parport.o
         
To load the architecture-dependent code to tell 'parport' code

			insmod parport_pc.o  io=0x378,0xc000,0xc800
			irq=7, irq=11, none

			or

			insmod parport_pc.o  io=0x378,0xc000,0xc800
			irq=7,11,none	

You have three PC-style ports, one at 0x378 with IRQ 7, one at
0xc000 with  IRQ11, one at 0xc800 with no IRQ.


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

 
 
 

Download Driver Pack

How To Update Drivers Manually

After your driver has been downloaded, follow these simple steps to install it.

  • Expand the archive file (if the download file is in zip or rar format).

  • If the expanded file has an .exe extension, double click it and follow the installation instructions.

  • Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.

  • Find the device and model you want to update in the device list.

  • Double-click on it to open the Properties dialog box.

  • From the Properties dialog box, select the Driver tab.

  • Click the Update Driver button, then follow the instructions.

Very important: You must reboot your system to ensure that any driver updates have taken effect.
