I just did ssh -vvv -- I saw no difference in what the client sends...
Go figure...

I can't see why the sshd would not apply both the same way.  But mind
you, the client is OpenSSH 2.9p2 on Solaris, and the server is OpenSSH
2.9p2 on OpenStep.

No big deal. The patch to add tio.c_iflag |= INLCR, tio.c_oflag |=
ONLCR and tio.c_lflag |= ECHO suffices for me. We've tested with
OpenSSH clients and PUTTY.
