  program: ECHOCOM.C
  use    : echocom [/pn] [/bm] [/to] [/ep]
	   where n is comport,may be 1 or 2 or 3
		 m is baudrate(2400-115200)
		 o is 0(command mode) or 1(Bypass mode)
		 p is 0(echo off) or 1(echo on)
	   (1) must run on 7188
	   (2) default baudrate is 9600 , default port is COM3
	   (3) In bypass mode, any data key in will be direct send to comport
	   (4) echo ON/OFF is used on bypass mode.
  function description:
	   (1) echo any data on the 7188's COM1/2/3 to COM4.
	   (2) data come from COM4(end with CR(0x0d)) will be send to
	       COM1/2/3(data in will be buffered,until receive 0x0d,
	       7188 will send out the buffered data.(if checksum enable,
	       will append checksum(2 bytes) after the data,before 0x0d.)
	   (3) press 'q'(not 'Q') to quit.
	   (4) press 's'(not 'S') to toggle checksum mode.
	       so 'q' and 's' will not be send to comport.
	   (5) default mode is checksum disable.
	   (6) protocal is 1 start bit,8 data bit,none parity,1 stop bit.
	   (7) when use COM2, echocom is the same as echo485
	   (8) press CTRL_A/B/C change to use COM1/2/3
           (9) input "*bxxxx" to change baudrate,where the xxxx is baudrate.
               for example: *b115200 change baudrate to 115200
                            *b9600   change baudrate to 9600 
[10/11/1999]
  Add show COM port,checksum,baudrate on 5-DigitLED
  position 1: 1/2/3 for COM1/2/3
  position 2: 0/1 for checksum OFF/ON
  position 3-5: 115--> baudrate=115200
		576--> baudrate=57600
		384--> baudrate=38400
		192--> baudrate=19200
		096--> baudrate=9600
		048--> baudrate=4800
		024--> baudrate=2400
		012--> baudrate=1200
		006--> baudrate=600
		003--> baudrate=300
[10/12/1999] Ver. 1.02
  Add bypass mode, in bypass mode can set Echo ON/OFF
  *p0 --> end of bypass mode
  *p1 --> to bypass mode
  *e0 --> echo off
  *e1 --> echo on
  Only on [Command mode] can use *p,*e,*b command.
  Press CTRL_E to toggle between COMMAND mode and BYPASS mode
[10/19/1999]
  use SetBaudrate1(),SetBaudrate2(),SetBaudrate3() to change baudrate.
