3.4. "Network" Mode
In this mode, several B900ss-20 Modems are able to communicate with each other.
Therefore, they constitute a Network handled by a Server Modem that can hold up to
16 Client Modems (6 in the actual V0.2 version).
The acquisition procedures, the modems synchronization and the RTS/CTS and Ack_Tx
signals handling are the same as for the "Point-to-Point" Mode.
On the other hand, when a frame is sent, it is necessary that a character indicating the
receiver modem number precedes the data frame. Also, in receiving the frame, a
character preceding this frame indicates the transmitter modem.
