Re: java type

[Richard Phillips]

If the buffer is indeed a string, you could also use Trim (or more 
specifically in this case, TrimRight) which removes leading and/or trailing 
whitespace (like #$D and #$A) from a string.

how can I delete the CR/LF pair:(#$D#$A)
Seems you are really new to Delphi !
You should probably post such question in a general purpose foru because 
it
is not really related to winsock !

Anyway, here is an answer:
What type is the variable where you get the data ?
If it is a string, you can simply reduce its length by two:
   SetLength(YourBuf, Length(YourBuf) - 2);
Or you can write safer code:
   if (Length(YourBuf) >= 2) and
      (YourBuf[Length(YourBuf)] = #10) and
      (YourBuf[Length(YourBuf) - 1] = #13)
   then SetLength(YourBuf, Length(YourBuf) - 2);
And there are also a myriad of ways achieving the same goal...
