Communications Module Protocol 
Communications Module Address 
Communications Module resync time (in characters).  Used for 
Communications Module protocols 2200 and 2179 to determine 
when one message ends and another message begins 
Communications Module Transmit Enable Delay (in milliseconds), 
Specifies the amount of time between the RTS output being activated 
and the start of transmit (output) data. 
Host Address for Unsolicited Responses 
Auto Inhibit Enables (Y) Remote Raise/Lower. If disabled, (N)
