It wasn't clear to me that you wanted to just discard the `\r`s, that makes things even simpler. Given that - yes, you can use a separate call to awk to remove `\r`s before piping to your real script or you can do what I suggested below but change `$0 ~ /^\r?$/` to `{ sub(/\r$/,"") } $0 == ""`.

but the RS issue remains
oh well up to better times somewhen else
thanks :)

Have you considered just writing code to decide if a pair of `\r?\n`s has
been seen instead of using a more complicated RS? For example, using the
default RS and ORS, I think this will do what you want:

$ cat tst.awk
$0 ~ /^\r?$/ {
     gotRS = 1
     lineNr = 0
!gotRS {
     # just keep appending to the record until the real RS is found
     rec = ( ++lineNr == 1 ? "" : rec ORS) $0
     # we have a complete record so save it in $0 and process as normal
     gotRS = 0
     $0 = rec
     print "<" $0 ">"
$ awk -f tst.awk

I'm sorry.

I give up.

You will have to use another approach. Maybe using gawk's built-in
networking will help.

Good luck.

  i just got now to it
in my testing on terminal still same bug, on testing that gawk > stderr
cmd even more newlines were needed to make it print ( on the tcpserv

term )

that makes it invalid for my httpd and the bug but ill just try now too

Please do

         make distclean
         git pull
         git checkout test-socket-patch
         ./bootstrap.sh && ./configure && make

I applied the patch and pushed it to git in that branch.
