1) readpic (which is used to read PROGRAM memory - EEPROM data memory is accessed by way of readdata) has options the wrong way round -
length is first and THEN address a la:
./readpic 512 0
(read first 512 bytes) - we see it matches monitor.hex
but are config bits set?
try 9v to Vpp/MCLR (pin 4) and erasepic - yes configuration bits erased
and with writepic they are programmed!
2) next step is to re-test serials...

The basic function of a pull-up resistor is to insure that given no other input, a circuit assumes a default value. Actually, there are two flavors of this circuit. A pull-up and a pull-down. Their function is the same, to create a default value for a circuit, but one pulls the line high, the other pulls it low.
1) Monitor-running PIC is powerd from regulated 5v supply with 10k resistor from Vcc to MCLR (pin 4) and 2.2 uF Tantalum across
Vcc/GND connected via MAX3232 circuit to second laptops serial port
2) Second laptop is loaded with darcs (yum install darcs) and then
brood. Running now brood -e purrr as before
2.5) (purrr sheepsint) restore
3) ping returns random stream of numbers or nothing
4) as per example for sheepsint:
( : click PORTB 3 toggle ; ) upload
either returns 7681 0012 FFFF FFFF
or:
7681 0012 7681 0012
And then the following: ( click ) trun
nada!
5) Troubleshooting:
a) PIC is badly programmed: verify using parallel port programming circuit!
b) hardware problem with PIC on breadboard (noise): make small veroboard circuit with socket and parts! test very basic code
c) or serial section: program PIC for standalone serial echoing say!
d) problem with serial port on laptop: ????
e) problem with cat/purrr: last step! revert to earlier pulls, test, debug
