I have a few questions about the linkport. I am slowly prepairing to renew the Starwar project, but since i don't have 2 calculators i'm going have to ask these questions and then hope its working when its realeased.

I allready know what data to send to achieve what but what i don't know is:
When im using bcall(_SendAByte, does the reciving calculator respond after each byte or does it just wait till it recognizes a combo of bytes to confirm?
And since the other calculator has to use ReciveAByte, what happens if i send a byte and try sending another one before the other calculator recives the first one?

When you use SendAByte, the bcall will succeed if a remote calculator acknowledges the byte, or fail otherwise. SendAByte only sends a single byte at a time across, and indicates the success or failure of each byte individually. The latter case that you mention is impossible.
