Now i found one problem and solved it.. but found another and SIGH not
solved...
The TXErrors were produced by the maxkeyup... now no problem with it...
but...
I've this problem now:
on scc0 (1200 baud) everything goes right. I can see the TXQueeu of the
port go up and down... It begin form seven, arrives at 2 now goes again
to 3 then 2 then 0... But no problem... everything works fine...
on scc1 (2400 baud) the thinf are different...
I can see 7 on TXQueue then it goes rightly down to 0... but...
After a time (i've not estimated to number of pkts but i thing abot 60) or
after the first reject something begins to go crazy...
Pratically... after the first rejct the scc send two grouips a pkt well...
then i see the number of txqueue pkts go up to 8.. then 10... then.....
then up to 24!!!
When there are a lot of packet scc sends only a part of them and doing a
sccstat scc1 i've noted that the amount of txqueue decreases without the
rtx on air... This is not caused by maxkeyup because iot sends on a few of
packwet...
This happens in a loop ... it arrives sometime to 10 , other time to 9
etc etc... Then it rebigins from seven (for two or three tx) and then the
amount of pkts is increased..
I also noted that when there are more then tha stabdard window size
packets on txqueue and everyone have sent, some of them are copied.
For example with maxfram = 2:
first ~20 rtx: all well
then: txqueue = 3, 1 pkt is duplicated (the foirst that has benn sent)
then: txqueue = 4, two pkts are duplicated (pratically all)...
then: txqueue = 6, only one or two pkts txed, txqueue decresas withut
keying the rtx
Then: the loop rebegins: but the first step contains about 3 pkts +- 1...
I've tried with both kernel default (case with maxfram = 2) and with
maxframe setted to 7....
Note that in thios moment i'm only using ax25 (i've tried in tcpip too and
the result is the same: duplication of pkts...)...
Infos for who is trying to get S5PCC functioning: i simply had some conf
problem somewhere (i don't know excatly where)... Now i'm using my p5
configuration and everything works fine... Just setting it as BAYCOM (USCC
cards)...Pratically the example configuration provided by Joerg DL1BKE....
Thanks...
