[DIYbio] Re: OpenPCR + Terminal: Any leads?

OK cool, so using the strace info (thanks Nathan!) and directing stuff
with hard-quoted (' rather than ") echo commands to the "CONTROL.TXT"
file in /media/OPENPCR, I got it to start a program and stop a program.

It's probable that last time I tried this and failed (ruling it out as a
possibility thereby), it failed merely because I was using the wrong
quotation mark: " only ignores spaces, but special characters like
slashes etc. still screw it up, whereas ' sends the literal enclosed
string without interference.

So, here's what I sent and had success with:
To start:
paragon@Tranquillity:~ echo -n
's=ACGTC&c=start&t=50&d=55709&l=96&n=IndieBB MCS
Check&p=(1[75|95|Initial
Step])(40[20|95|Step][10|60|Step][32|70|Step])(1[120|70|Final
Step][0|4|Final Hold])' > /media/OPENPCR/CONTROL.TXT

To stop:
paragon@Tranquillity:~ echo -n 's=ACGTC&c=stop&t=50&d=55710' >
/media/OPENPCR/CONTROL.TXT

The program syntax can be deciphered from the first command.
All commands start with 's=ACGTC'.
The '&c=start' part says to start with the ensuing program.
Not sure what '&t=50' or '&d=55709' mean.
'&l=96' means set lid to 96C.
'&n=IndieBB MCS Check' means set the displayed name to "IndieBB MCS Check".
'&p=(<Initial>)(<Cycle>)(<End>)' is the program itself.
