DWAIT n (n = 0 - 255)
Multi-Port
default 0/0
DWAIT defines a delay to be used to avoid collisions with digipeated packets.
The value entered for “n” is the number of 10 ms intervals, after last hearing data
on the channel, for the TNC to wait before it begins its own key-up sequence.
This value should be established and agreed on by all members of a local area
network. The best value will be determined by experimentation but will be a
function of the key-up time (TXDELAY). This feature is made available to help
alleviate the drastic reduction of throughput which occurs on a channel when
digipeated packets suffer collisions. Digipeated packets are not retried by the
digipeater but must be restarted by the originating station. If all stations specify
DWAIT, and the right value is chosen, the digipeater will capture the frequency
every time it has data to send since digipeated packets are sent without this delay.
Observations have proven that a better algorithm for avoiding collisions between
end-user stations, while still allowing digipeaters the high-priority access they re-
quire is achieved using Persistence and Slottime to determine proper transmit in-
tervals, and setting DWAIT to 0.
