The Following files will be there with the tar of the Driver:



	mcs9865.c

	mcs9865.h

	mcs9865-isa.c

	mcs9865-isa.h

	Makefile

	README	

	mcs9865



Building the Driver:

--------------------

	Change to the folder with the Starex source files. And run the following Command:

		$ make



	Once the driver is compliles the loadable module mcs9865.ko will be created in the same folder.



	**  '$' --this symbol represent the shell prompt on linux			



Loading the Driver:

-------------------

	

	To load the driver use the following command:

		$ insmod mcs9865.ko

		$ insmod mcs9865-isa.ko



	**  '$' --this symbol represent the shell prompt on linux			



Unloading the Driver:

---------------------



	To unload the driver use the following command:

		$rmmod mcs9865

		$rmmod mcs9865-isa



	**  '$' --this symbol represent the shell prompt on linux			



Installing the Driver:

----------------------



	To install the driver use the following command:

		

		make install



Uninstalling the Driver:

------------------------



	To un-install the driver use the following command:

		

		make uninstall



Note: only baud rates upto 3.0Mbps are implemented in the current driver.

	

Feature Configuration:

----------------------



	This driver comes with a static array uart_9865_contxts[ ] for all the 16 ports features in the 9865.c file.

	Where u can set the features like:

		-DMA in RX

		-DMA in TX

		-enable/disable Flow control

		-Flow control type

		-RX fifo trigger level

		-TX fifo trigger level

		-x-on character

		-x-off character



	An example array setting for PORT 0 which will be recognised as /dev/ttyD0:			



	//Port 0	--**This represents that this setting is for port 0 which will be recognised as /dev/ttyD0

	{

		.rx_dma_en	= 0,

		.tx_dma_en	= 0,

		.uart_mode	= MCS9865_RS232_MODE,

		.en_flow_control	= 0,

		.flow_ctrl_type 	= MCS9865_XON_XOFF_HW_FLOWCONTROL,

		.rxfifotrigger	= 64,

		.txfifotrigger	= 64,		

		.x_on		= SERIAL_DEF_XON,

		.x_off		= SERIAL_DEF_XOFF,

	},



	To change it to different modes like RS232 and RS422, we have to fille the .uart_mode with corresponding //UART mode defined in header files. for example for setting it to RS422 mode, we have to fill .uart_mode=MCS9865_RS422_MODE.





Kernels:

--------



	This driver is currently developed and tested on 2.6.11 linux kernel and above 	



Limitations:

------------



	This driver supports a maximum of 16 serial devices. This can be modified as required		







Steps for setting parallel port :	

---------------------------------

	1. rmmod lp

	2. rmmod parport_pc

	2. insmod /usr/lib/modules/2.6.15/kernel/drivers/parport/parport_pc io=0xb000 irq=10.



Note: Here, the io and irq should be noted from lspci -v.
