基于uIP框架的8051tcpip源码

Comments about uIP porting to 8051 by Fajun Chen 

8051WEB is the porting of uIP to 8051 by Fajun Chen. It was tested with 
Windows2000 Professional.

1. Instruction for setting up Windows2000 Dial-up Network:
   Please refer to http://www.iosoft.co.uk/docs/win2k.doc. Notice that 9600 bps is
   used for 8051WEB and default IP forwarding should be disabled.
    
2. Dunfield's Micro-C Compiler
   Please purchase full version from http://www.dunfield.com. Demo version is not
   enough for the code size.
   
   Function thermoread() need to be added into I2C.ASM and compact.lib in Micro-C 
   LIB51 directory for reading temperature from DS1629. The function is as follows:
   *
   * Read temperature from DS1629: thermoread();
   *
   thermoread	MOV	R6,#0		Zero retry count
   ?9		MOV	A,#%10011110	Control byte for WRITE
   		LCALL	?ICstrt		Start transfer
   		JNC	?A		Its OK
   		DJNZ	R6,?7		Do full retry
   		SJMP	?4		Report error
   ?A		MOV	A,#%10101010	Read temperature protocol
   		LCALL	?ICsend		Write
   		JC	?4		Report error
   		MOV	A,#%10011111    Control byte for READ
   		LCALL	?ICstrt		ReStart transfer
   		JC	?4		Report error
   		LCALL	?ICread		Get data byte
   		MOV	B,#0		Zero high
		SJMP	?ICstop		Stop transfer		

3. Build Instruction in DOS:
   Please use GNU make, 
   >make uweb.hex

4. Code Porting Summary
1) Replaced typedef with #define since typedef is not supported by Micro-C
2) Increased UIP_BUFSIZE 
3) debug buffer is defined for debugging which replaces printf()
4) Lots of struct type related changes (Struct support in Micro-C is
   quite limited, it's implemented similar to char array).  
5) Fix the bug with handling the URL with index.html
6) fsData initialization is moved to fsdata_init() function. Perl script makefsdata
   should be updated for code autogeneration.
