Figure 9-3. Hostlist Option 
 
To enable the hostlist: 
1. Enter 
Connect Mode
 of 0x20 (2X), where X is any digit. The menu shows you a list 
of current entries already defined in the product.  
2.  To delete, modify, or add an entry, select Yes. If you enter an IP address of 0.0.0.0
that entry and all others after it are deleted.  
3.  After completing the hostlist, repeat the previous step if necessary to edit the hostlist 
again.  
4. For 
Retrycounter
, enter the number of times the Lantronix unit should try to make a 
good network connection to a hostlist entry that it has successfully ARPed. The range 
is 1-15, with the default set to 3
5. For 
Retrytimeout
, enter the number of seconds the unit should wait before failing an 
attempted connection. The time is stored as units of milliseconds in the range of  
1-65535. The default setting is 250
d) Datagram Type 
Directed UDP 
When selecting this option, you are prompted for the Datagram type. 
Enter 01 for directed or broadcast UDP.  
 
When the UDP option is in effect, the unit never attempts to initiate a 
TCP connection because it uses UDP datagrams to send and receive 
data. 
e) Modem Mode 
In Modem (Emulation) Mode, the unit presents a modem interface to the attached serial 
device. It accepts AT-style modem commands and handles the modem signals correctly.
