1.1.2 MEWNET - W2 Mode
Large volumes of data can now be transmitted over long distances.
Link communication can be carried out between various FP2 units, using link relays and
link registers.
Communication limited to only FP2 units is possible.
Using the MEWNET - W mode increases the volume of data that can be handled.
Using the MEWNET - W mode extends the transmission distance (when set to 250 kbps).
The link relay and link register areas used for PC link communication are specified using
user programs.
