Unofficial Name: Get4Bytes
BCALL Address: 4EF4
Receives 4 bytes over the link port.
- Bytes received to header
This BCALL will throw ERR:LINK if any problems are found. It does not receive just any 4 bytes; it must be the beginning of a valid packet, meaning it must contain a valid machine ID.
It is useful to BCALL this before some of the other link routines (specifically, the ones which do not receive the first 4 bytes for you).
