RS232 commands 115200 Bd 1 start bit, 8 data bits, 1 stop bit:\n\r
\n\r
AnnnnENTER   set data pointer in data EEPROM, range 0 to 32767, saved in EEPROM.\n\r
C            debug mode on, reads and prints ADC values and current PWM value continuously.\n\r
c            debug mode off.\n\r
DnnnnENTER   set day.\n\r
E            dump external EEPROM data.\n\r
FnnnENTER    select data EEPROM, 160 or 162, default 160.\n\r
f            print selected data EEPROM.\n\r
GnnnENTER    set clock calibration, set timer1 reload, default 219, saved in EEPROM.\n\r
HnnENTER     set hour.\n\r
h            help, this help.\n\r
InnENTER     set seconds between PWM increase or decrease by temperature controller, 1/igain, default 1, saved in EEPROM.\n\r
MnnENTER     set minute.\n\r
PnnnENTER    set PWM pulse width start value, saved in EEPPROM.\n\r
s            print PWM, clock calibration (timer1_reload), time, temperature setpoint, igain.\n\r
TnnnnENTER   set temperature setpoint, saved in EEPROM.\n\r
WnnnnENTER   write 3 bytes data, the first 2 as word nnnn, the third zero, to data EEPROM selected by F, at address set by A.\n\r
w            reads 3 bytes data, the first 2 as one word, from external EEPROM at address set by A.\n\r
Y65535ENTER  restart acquisition at zero, resets clock and data pointers to zero, data in external EEPROM is left untouched until one hour passes.\n\r
