it says test:27 unssoported mode

if can help, im using computercraft 1.52 in minecraft 1.5.1 with the last forge (7.7.1) and i have installed NEI, galacticraft and rei minimap on windows 8 x64

[theoriginalbit]

file = fs.open(filename, "rb")

Have a read http://lua-users.org...LibraryTutorial http://www.lua.org/pil/21.2.2.html

EDIT: Whoops, wrong link.

Now the code doesnt send anything, and the ping line is always turned on, even if the program is closed

[theoriginalbit]

what exactly is this program meant to be doing?

It would be easier to read this if you could space a little better, not trying to be rude, but it would help if you were to space this better, it would let us read your code better and help you faster.

Has does sleep(0) allow redstone to do anything... I told you this in IRC. It has to be (I believe) at least 0.2 seconds.

0.1 actually... thats a single tick, which is the fastest a rs signal can be on. So do you know, what is the purpose of this code? and why does it need to be open in binary mode?

He's trying to send/receive a file through 2 redstone wires, through binary.

Also the reason why the ping line is always on is because you never then turn it off Redstone outputs are not pulses, unless you make them pulses by alternating between setoutput true and setoutput false

Ahh i see... thanks...

well... you will encounter a problem when attempting to write the string out to the file when it is opened in binary mode. you will need to get 8 pulses (bits) and then encode them into a byte and write it to the file. also how does it know when the file is finished copying across? You need to setup some kind of bit count at the start of the stream, or you need to setup some kind of terminating byte that is sent across so it knows when it is the end...
