Any way to set endpoint buffer size on panda

Could some of this (in SYSTEM:7-CONFIG.CMD) be what you are looking for?
This is from RARITY (not PANDA, but DEC vanilla distribution,kind of), I'm
not sure I have the correct values myself, been experimenting.
; DECnet parameters:
;default is DECNET BUFFER-SIZE 576
decnet buffer-size 1476
;default is DECNET MAXIMUM-BUFFERS 80
;decnet maximum-buffers 40
Hmm. That do not seem to be the values currently used:
.ncp tell rarity sho exec cha
Node characteristics as of 14-JUL-24 10:58:22
Executor node = 1.802 (RARITY)
Identification = Rarity of Maneframe Six
Management version = 4.0.0
Software identification = DECnet-20 Version 4.0
Loop count = 1, Loop length = 127
Loop with = Mixed
Incoming timer = 30, Outgoing timer = 60
NSP version = 4.0.0
Maximum links = 65535, Delay factor = 48
Delay weight = 10, Inactivity timer = 120
Retransmit factor = 10, Routing version = 2.0.0
Type = Routing IV, Routing timer = 600
Broadcast routing timer = 40
Maximum address = 1023, Maximum circuits = 20
Maximum cost = 100, Maximum hops = 16
Maximum visits = 20, Maximum broadcast endnodes = 64
Maximum broadcast routers = 32, Maximum buffers = 80
Buffer size = 576, Segment buffer size = 576
.
However, also to clarify some things. The segment buffer size should
probably stay at 576. This is basically the size of packets used at the
DECnet level, and I have some vague recollection that nodes should use
the same size, or DECnet might fail. DECnet is not that clever about
different sizes there.
The buffer size on the other hand can be larger (modulo VMS bug that I
mentioned a few days ago), but that would only be used by link layer
protocols, like the routing information packets that are sent, for example.
But if you are experimenting, please let me know if you figure something
out. Positive or negative. Always good with more information.
