Case 3 – STAR Modem™ in STAR-System™ Mode as Server 

 

 

 

Figure 3 – STAR-System™ Mode 

 
Both STAR Modems™ are in STAR-System™ Mode and are therefore able to 
communicate bi-directionally. For analysis purposes only, we assume the situation 
where Host 1 is Client and Host 2 is Server. It is clear that the situation is analogous 
in the opposite direction: 
 

• 

If Modem 1 - 

Transmission Mode = 1 way 

 

ACK/NACK from Remote Host = disabled 

 

FIFO = enabled 

 

Handshaking = any 

 
 

The Client, (Host 1) sends a message to the Remote Host (Host 2), but no 
control exists upon reception and even if ACK/NACK Protocol is implemented on 
the Server side (Remote Host), no answer is returned from Modem 2 to Modem 
1 (except for a single blink from the red LED on Modem 1). This is not a secure 
communication. 

 
 

• 

If Modem 1 - 

Transmission Mode = 1 way 

 

ACK/NACK from Remote Host = enabled 

 

FIFO = enabled 

 

Handshaking = any 

 
 

The Client, (Host 1) sends a message to the Remote Host (Host 2). Modem 2 
acknowledges good radio reception but no control is made on Remote Host 
reception. If Modem 2 acknowledges radio reception within the Radio Protocol 
Timeout, Modem 1 sends ACK to its local Host, otherwise it sends NACK.
