The routing above is very confusing, w6yx.ampr.org = 44.4.0.196 so he is a
"host" not a "net"
route add 44.4.0.196 window 128 irtt 2000 dev sm0
would be more applicable i think. (See comment on wondowsize below)
You attach a route for 44.0.0.0 via sm0 as the first route, however after
adding the bogus route to 44.4.0.196 you add a default route for 44.0.0.0
again but now via 44.4.0.196 who at firstsight is a "net".
I would do the following.
ifconfig sm0 down # clears routing.
ifconfig sm0 up # should use the old configured address etc.
ifconfig sm0 braodcast 44.255.255.255
route add 44.4.0.196 window 128 irtt 2000 dev sm0
route add -net 44.0.0.0 netmask 255.0.0.0 gw 44.4.0.196 sm0
On another note you define a MTU of 512 which carries 472 bytes of data,
you then configure a window size of 128 which is incompatable, a beter size
would be 944 which is 2 packts every transmission.
If you are worried about transmitting and receiving Too large packets, then
lower the MTU to 256 and set the window size to 216 thats one packet.
Now i hope i got my sums right.
