Handshaking
This message provides a mechanism for synchronizing certain aspects of one system to another. The
most significant use of this is during bulk dumps to a system where the transmitting unit (an external editor,
another MPX 1, etc.) could conceivably send the data too fast for the receiving system to process it. In
these cases the receiving system transmits a BUSY handshake message while it internally processes the
last dump. When it is ready to receive more data it transmits a READY handshake message. This allows
data to be transmitted at the fastest possible rate without corrupting the data (buffer overflows, etc...).
