This field selects the type of transfer that the modem defaults to at power up.  
This will remain as the transfer type until it is switched using the appropriate 
control string. 
 
Selection Description 
Individual Transfer 
This is a standard point to point data transfer with 
acknowledgments. 
Individual Transfer 
w/o Acknowledge 
This is a point to point data transfer but without any 
acknowledgments.  This implies that there are no transmit 
retries if the packet is received with errors. 
Group Broadcast 
This is a broadcast to a group of modems.  Receiving 
modems will accept two types of group broadcasts.  
 
Group broadcasts - Broadcasts where the destination 
group matches the receiving modem's group.   
 
Multicast broadcasts - Broadcasts where the 
destination group matches a group from the receive 
modem's multicast group list.  For these broadcasts to 
be received, the receiving modem must have multicast 
reception enabled. 
Network 
Broadcast 
This is a broadcast to all modems.
