the packets waiting to be digipeated will be subject to the same wait times as not-to-be-
digipeated packets awaiting transmission.
By subjecting ―special‖ to-be-digipeated packets to a delay determined by slottime
and persist, it is more likely that to-be-digipeated packets of two or more stations in
the same vicinity would not collide. This may be good if one wants to guarantee that
a digipeated packet will ―make it out‖ of its neighborhood but bad if one wishes to
limit the number of times a packet is redigipeated, such as in APRS applications.

UIFLOOD name[,time[,{FIRST | ID | NOID}]] (name = 5 char max)(time = 0-255)
default disabled,30,NOID
When a UI frame is received with a call in the to-be-digipeated field of the form ‗name‘
x-y where x is a number (1-7) appended to ‗name‘ and y is an ssid (1-7), the ssid is
decremented and the UI frame is digipeated without setting the H bit. When the packet
is digipeated, a checksum is formed over the source, destination, and data fields of the
packet. This checksum is kept for time seconds (0-255). If an incoming UI packet is
eligible for digipeating as above, but its checksum matches one of those being saved,
the packet is discarded (not digipeated). The buffer holds a maximum of 64 checksums.
If the optional parameter ID is selected, the MYCALL call sign is inserted in an
additional digipeater address field with its H bit set.

UITRACE name, n (name = 5 char max)(n = 0-255)
default disabled, 30
When a UI frame is received with a call in the to-be-digipeated field of the form ‗name‘
x-y where x is a number (1-7) appended to ‗name‘ and y is an ssid (1-7), and MYCALL
does not appear in the source field or any of the has-been-digipeated fields, MYCALL
with the H bit set is inserted before the to-be-digipeated field, the ssid of the to-be-
digipeated field is decremented, and the UI frame is digipeated without setting the H bit
of the to-be-digipeated field. The value of n sets a delay time between duplicate
digipeats. Use of this ―do not duplicate within n seconds‖ feature helps control the
number of UI frames digipeated.
If the packet should already have 8 digipeater fields, MYCALL is not inserted.
