Synopsis
Unofficial Name: CheckLinkLines
BCALL Address: 4F4E
Checks the link port data lines to see if they match the value in A.

Outputs
- Z set if link port is same value as in A
Destroys
- All
Comments
This is a pretty dumb entry point. I suppose it could be checking for a stable link. The OS link activity hook uses this.
