Sync communications

I have been working on a project for about 3 days and I can’t seem tofigure this out.
I have a board that has a 6 pin RJ25 port on it.
The pin outs are as follows:
·
1 – Ground
2 – Ground
3 - +5v
4 – Data (out)
5 – Clock (in)
6 – Ground
·
OK I think we all can handle pins 1,2,3 and 6.
Unfortunately I know no more than you do now about pins 4 and 5.
This sounds like some type of synchronous communication, maybe TTL ofsomething.
·
Well instead of me guessing, does someone know how I might be able toread pin 4 and what do I hook to pin 5?
·
Thanks,

have to generate the "clock".
If you are saying to output the clock say on Pin 7 with the pulseout command
then how do I read the data on Pin 5 coming into the stamp?
Pulseout 7,## // if this line generates the "clock"

I would think a pulse of 5V on pin 5 would give you a bit of bit of data
on pin 4.
