Ver1.12
1. Add CP-102UF model.
2. Support kernel up to 2.6.21.
3. Support to set baud rate by setserial.

Ver1.11
1. Add CP-114UL model. 

Ver1.10
1. Add seven models.
   CB-108, CB-114, CB-134I, CP-118U-I, CP-138U, CP-138U-I, POS-104UL

	In previous version of driver, if the card is not 8 ports product, the driver will assign it as 4 ports product.
	Therefore, the driver recognized incorrect port numbers in all 2 ports ISA products.
	The bug is at the mxser_get_ISA_conf() function.
10. Support non-standard baud rate.
11. Programming guide for special baud rate:
	
   - Define the I/O control code.
    
	 #define  MOXA_SET_SPECIAL_BAUD_RATE  0x44D 	
	
   - Using the ioctl() API to set non-standard baud rate after 
     setting the termios parameters.
	  
	 int  baud; 
	 baud = 500000;  /* set the non-standard baud rate */
	 ...
	 tcsetattr(fd,TCSANOW,&t);

	 ioctl(fd, MOXA_SET_SPECIAL_BAUD_RATE, &baud); 
12. Support kernel up to 2.6.17rc1, including Fedora Core 5.

   can see rc.mxser for reference.

   - mxser_receive_chars()
   - mxser_transmit_chars()
   - mxser_check_modem_status()
12. Fix system halt problem under SuSE 9.1 +2.6.5-7.108smp.

Ver1.8
1. Offical Release.
2. In this version, use "modprobe mxser" to load driver instead.
3. Speed up msmon load time.
4. Fix system halt problem while traffic is heavy (for ver1.7.7).
5. Fix low performance problem on PCI board (for ver1.7.7). 
6. Linux 2.0.x & 2.2.x doesn't support any more from this version.
7. cum* device is obsolete under Linux kernel 2.6 (but still also
   availabe under Linux kernel 2.4). Use ttyM* device instead.
8. Support MOXA powered UART MU860. This can enhance CP-168U/CP-104U/
   CP-104JU v2 performance & function (on-chip SW flow control,
   up to 921.6k baud rate, 128 bytes FIFO).
9. Newly support CP-118U, CP-102U, CP-102UL.  
10. Support Linux 2.6.x.
    a. For RedHat AS/ES/WS/Fedora Core 1 (not for Core 2):
	 # make installsp1 
    b. Use "insmod ./mxser.ko" under mxser\driver, not "insmod mxser".
11. Fixed the Tx/Rx problem when using ISA Boards.
12. Fix compiling problem under Red Hat AS/ES/WS/Fedora Core 1.
    To fix this problem, the compiling option must be changed from "install" 
    to "installsp1". 

   - original -
	# cd <installed> directory
	# make install 
	# ...

   - new -
	# cd <installed> directory
