customizing putty source code -- 2

I want to have client entered command in a file once a command has been entered. The project should be fully compatible with all ssh standard like VT-100, xterm and so on. Also multiple line command should be logged with no enter character inside. Imagine client connected to a ssh server via the customized putty and enter the blow command in it: sudo ntlm_auth --request-net-key --challange="AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA" --nt-responce="BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB" I would like to have the command in a file once it is completed without any intermediate '\n' or '\r' Please consider that it is only an example command. I need to have all commands regardless on its length (which may be one line or multiple line) in that log file without any intermediate '\n' or '\r'. Also please consider that the size of pty may changed by client and this should not mixed your code.
