////  This program uses both the KBD.C and LCD.C drivers to allow    ////
////  keypad entry and LCD display.  All keys are echoed except *    ////
////  that will clear the display.  Either the kbd_getc or lcd_putc  ////
////  may be replaced with getc or putc to use just one device with  ////
////  the RS-232.                                                    ////
////                                                                 ////
////  Configure the CCS prototype card as follows:                   ////
////     Plug in both the LCD and KEYPAD.                            ////
////                                                                 ////
////  This example will work with the PCB, PCM and PCH compilers.    ////
////  The following conditional compilation lines are used to        ////
////  include a valid device for each compiler.  Change the device,  ////
////  clock and RS232 pins for your hardware if needed.              ////
