  printf.c    ------   demo program for 7188

  demo program for use function printCom4.
  the use of printCom,printCom1,printCom2,printCom3,printCom4 are all
  the same as C function printf. The internal buffer is 160 bytes, so
  user cannot use printCom(1/2/3/4) to print a message longer then 159
  characters.

  printCom(1/2/3/4) are useful for user to send formated message to comport
