Re: read-write to stdin-stdout or to a file?
Quoting Pedro Zorzenon Neto (pzn@terra.com.br):

Do you mean this package?
"Programmer for Atmel AVR microcontrolers that uses PC parallel port
to program the device in serial mode. The device can be programmed
"in-system". It comes with a schematic of the hardware required.
The hardware was designed to be efficient and unexpensive."
If so, I'm not sure why you think it needs to be setuid. Just
chgrp somegroup /dev/lp0 (or whichever port) and put yourself
(and any others) into somegroup.
