1. VXC multi-serial cards hardware feature

1.1 VXC-142
The VXC-142 card provides two independent RS-422/RS-485 serial ports. 
Each port can be configured as either RS-485 or RS-422 for half-duplex 
or full-duplex communication. The COM port number can be fully 
auto-defined or defined serially by hardware with dip switches to set  
the first number.
In the harsh industrial environment, the on board surge protection can 
protect the computer and equipment from being damaged by high potential 
voltage. Along with the basic communication feature, the VXC-142i can 
withstand isolation voltage up to 3KV. 

1.2 VXC-182i
The VXC-182i serial card provides two communication ports, one is 
RS-422/485 and the other is RS-232 port. It offers speed up to 115.2Kbps 
and long distance communication link.
In the harsh industrial environment, the on board surge protection can 
protect the computer and equipment from being damaged by high potential 
voltage. Along with the basic communication feature, the VXC-182i can 
withstand isolation voltage up to 3K Vdc.


2. Driver feature
Device file. 
Dynamic device allocation. 
Dynamic major number. 
One major number for multiple devices. 
Use the GNU configure and build system. 

3. Installation
Download and save IxCOM package to a directory that you have access to. 
Extract the package. For example, the package's file name is 
"ixcom-0.05.0.tar.gz" and its path related to your current working directory 
is ../pkg, then the extraction command would be

	gunzip -c ../pkg/ixcom-0.05.0.tar.gz | tar xvf -

		or

	tar -zxvf ../pkg/ixcom-0.05.0.tar.gz 
	
	An ixcom-0.05.0 directory is created after extraction. For convenient 
	access, it is a good idea to put a symbol-link on it.
	
	ln -s ixcom-0.05.0 ixcom
	Change working directory to the ixcom you just made, type 
	./configure to create proper Makefiles. 

Once the configuring has done successfully, type make to build all. 
If you like to install files to system directory, the make install will 
do it for you. However, install files to system directory is not necessary 
for further operation. You will need the root privilege for that. 
Script ./ixcom.inst loads modules automatically. Script ./ixcom.remove 
removes the loaded modules. The root privilege is required when installing 
or removing these kernel modules. 

Please read file README if it is there.
