5/28/09 This is the Beta 0.1 driver for Exar PCI (17x15x/17v25x based) devices for QNX OS. Note: The module is built for “x86” platform. Installation: -------------- 1) Copy the file “devc-xrserpci” (which is in the zipped folder) to your QNX target system /sbin. 2) Open a Terminal in your QNX target system and change the current working directory to the folder where “devc-xrserpci” copied. 3) Type “./devc-xrserpci” and Enter. This will display the driver version and also the number of Exar ports found in the system. If 8 Channel board is connected, the message displayed will be: Exar’s devc-xrserpci QNX-module Beta ver 0.1 – May 28, 2009 8 Exar ports found. If no Exar PCI device is in the system, you will get: Exar’s devc-xrserpci QNX-module Beta ver 0.1 – May 28, 2009 “No Exar PCI serial boards found.” message.) 4) If the Exar ports are found, check the “/dev” folder for the newly created device names. Generally the device names will be “/dev/ser3”, “dev/ser4”, etc. (/dev/ser3 will be the first port of the PCI device, if there are 2 built-in serial ports in the system. If there are no other serial ports in the system except for Exar PCI card, then the Exar UARTs will start from /dev/ser1 ) 5) To Setup baud rate: To configure the serial port to any baud rate, the following command needs to be used at the console. 'stty baud= < /dev/ser1-8" where means the specific baud rate. Valid baud rates are 9600,19200,38400,57600,115200,230400. As an example, to set the baud rate of 9600 on serial port 3, the command looks like stty baud=9600 < /dev/ser3 similarly to set serial 5 to 115200 baud, the command would look like stty baud=115200 < /dev/ser5 NOTE: It is recommended to use the above command to set and configure the serial ports to the configuration desrired in the application. Testing: ------------- These serial ports can be tested, evaluated, used, just like a regular serial port. For initial testing, you can loop back from Port-1 to Port-2, and use cat/echo commands, as below, in the Terminal windows Terminal 1: Type “cat < /dev/ser3” and press Enter. Terminal 2: Type “echo “hello there!” > /dev/ser4” and press Enter If the board and the driver are properly loaded and working, and Port-1 is connected Port-2, you will see “hello there!” in Terminal 1.
