SCT is a usefull gnu tools to debug and trace serial port communication
Here are the documents help you to install and use uct

I How to make and install sct
 1 For linux platform or cygwin
    cp mk_linux Makefile
    make clean
    make 
    make install
 
 2 For Sco-Unix platform

    make install
    
II Quick guide to commands' of sct
        At the time you run the sct,you may input the command 
    by the right at the prompt "=>". you may input "help"+command_name
    for more detail.

 1  "?"
        to get command list

 2  "help" 
        for detailed help for the command
            usage: help command_name
               eg: help sel
                   get help of sel command 	

 3  "stat" 
	dsplay current port status 	
	    usage: stat

 4  "sel" or "port"
	select a serial device as current port 
	    usage: sel device 		
	       eg: sel /dev/ttyS0 
	
 5  "frame"
	set frameset 						
	    usage: frame rate,parity,databits,stopbits 		
	       eg: frame 9600,n,8,1
	
 6  "handshake" or "hs"
	set handshake for port communication 
	    usage: handshake [+/-] prototol		
	       eg: handshake +rts	
	            enable rts control		
	       eg: handshake -xonxoff	        	
	            disable xonxoff control
	       eg: handshake none
	            disable all hardware and fllow control
	
 7  "open" 
        open current port and active it

 10 "echo" 
	enter echo mode, reply all byte when received 
	    usage: echo
	
 11 "setbuf"
	set buffer data,10 buffers can use inall		
	    usage: setbuf buffer_no input_form 			
	       eg: setbuf 1 asc 				
	             set data of buf1 as ascii char		
	       eg: setbuf 2 hex 				
	             set data of buf2 hex code 
 12 "dispbuf" 
	display buffers' info or buffer's data 		
	    usage: dispbuf [buffer_no]				
	       eg: dispbuf 				
	             get infomation ablout all buffers	
	       eg: dispbuf 3			 			
	             display data of buffer 3 by both ascii and hex form
	
	
 13 "clrbuf", 
	clear the buffer					
	    usage: clrbuf buffer_no|all 			
	       eg: clrbuf 3					
	             clear buffer 3				
	       eg: clrbuf all                 			
	             clear all buffers
 14 "loadbuf" 
	load data to buffer from file 			
	    usage: loadbuf buffer_no filepath

 16 "copybuf"
	copy buffer from one to another 			
	    usage: copybuf dest_buffer_no src_buffer_no 	
	       eg: copybuf 3 4 					
	             copy buffer 3 to buffer 4
 17 "recv" 
	recv data to buffer,10 buffers can use inall		
	    usage: recv bufffer_no 					
	       eg: recv 4 					
	             recv data to buffer 4
