Typically LF is sent when Return key is hit. But for sshd servers that
sent us via ANSI escape sequence that CRLF is to be sent, ssh.exe client
will do so which is used commonly used by sshd servers in Windows - like
our own win32 port sshd.
Console API is now used for interactive tty mode. Thus ssh.exe client
can now pass each character to remote side as one types so that programs
like more works correctly. Control-c now will stop the remote program
instead of exiting the ssh.exe.
