Set Maximum Number of Remotes (base only)
 
This parameter limits the number of remotes that can register with a given base.   The 
default is 62 remotes which is the maximum number of remotes that can be registered 
with a base at one time. This command is useful when used in conjunction with 
global roaming for load balancing when base stations are collocated. It is also useful 
to assure a minimum remote throughput. 
Set Packet Attempts Limit
 
If ARQ Mode is set to 0, sets the number of times the radio will attempt to send an 
unsuccessful transmission before discarding it. If ARQ Mode is set to 1, it is the 
number of times every transmission will be sent, regardless of success or failure of a 
given attempt. When this parameter is set to FFH, RF flow control mode is entered 
for transmissions from the radio (See Section 2.3.4). This mode can be entered for 
one or both radios in a point-to-point system. Using this mode in a point-to-multipoint 
system will stop transmissions to all radios when any one radio has a full buffer. 
Set Data Transmit Delay
 
When used in conjunction with the minimum data length parameter, this sets the 
amount of time from the receipt of a first byte of data from the host until the radio 
will transmit in transparent mode.  Default is 00H which causes transmission to occur 
without any delay.  When a host is sending a group of data that needs to be sent 
together, setting this parameter will provide time for the group of data to be sent by 
the host before the radio transmits.  If the length of data to be sent together is longer 
than the time slot can send, the data will not be sent together but will be broken up 
over multiple hops.  The length of time the radio will wait is equal to the specified 
value times the hop duration.
 
Set Slot Assignment Mode (base station only)
 
Sets whether the base station will assign remote transmit slots dynamically, based on 
the number of remotes currently registered or whether the base station will assign 
remote transmit slots staticly, based on the maximum number of remotes parameter. If 
static slot assignment is selected, make sure maximum number of remotes is correctly 
set. Otherwise remote transmit performance will suffer as transmit time will be 
reserved for remotes that may not exist. The dynamic assignment mode will generally 
be preferred; however, the static assignment mode will result in a static maximum 
data length
  parameter.
