[pskmail] Re: Testing results of server 1.0.6 Alpha

Tnx John, these are all initialization issues, I will put some defaults into 
the alpha version.

The third issue is ok, the server should answer in default  mode, we get chaos 
otherwise 
as soon as we have more than one server on a frequency. (there are 5 servers on 
10147 over 
here....)

I am still working on the DCD issue.
We see a lot of collisions on frequency,  the main reason is that all servers 
reply at the same time 
and the time between sending the message to fldigi and decoding the other 
server's frame 
is quite long especially for modes like PSK500R.
I am experimenting with the Persistence system used in Packet Radio which does 
the following 
before sending the frame:
0 Wait until DCD is off
1 Generate a random number of 0...4
2 If the random number is not 0, wait 2 seconds (frame time overhead) and goto 0
3 if the random number is 0, send the frame

This will give some defense against collisions as the severs will start at 
different times 
most of the time...
Disadvantage is that noise or qrm will block transmission, but I think that is 
fair policy 
on a shared frequency...

>Rein,

Results so far:

1. At launch I get the following error messages:

2. During a connected session I get the following errors repeatedly: 

cat: /home/jdouyere/.pskmail/.band: No such file or directory
Argument "" isn't numeric in sprintf at 
/usr/local/share/pskmail_server/[arq.pm] line 4681.

Adding a file .band in .pskamail with a string of 80 for example stops this 
issue.


3. Unproto messages sent in a mode different from the default one (psk250r) 
results in replies in other modes like a PSK250R ping will be replied in 
PSK125R.

John
