There is a test suite which attempts to validate whether or not an emulation

It's me or the Tmesis ASCII-art logo appears somewhat scrambled? I'm using
PuTTY 0.62 (the latest) on Windows XP. I've tried more than once before
writing this, and got the same result either with a 80x24 terminal size, or
with a full screen PuTTY window that gives more or less a 120x60 terminal.
OK, just to be sure I looked at the raw data with tcpdump and there is really
a CRLF where I think it should not:
0x00b0: 316d 6d71 716b 2020 206c 7171 7171 7171 1mmqqk...lqqqqqq
0x00c0: 7171 7171 7177 7171 7171 7171 7171 7171 qqqqqwqqqqqqqqqq
0x00d0: 7177 7171 7171 7171 7171 7171 7177 7171 qwqqqqqqqqqqqwqq
0x00e0: 7177 7171 7171 7171 710d 0a71 7171 7175 qwqqqqqqq..qqqqu
0x00f0: 1b28 421b 5b30 3b31 6d20 2874 6d29 1b5b .(B.[0;1m.(tm).[
The above is the second Tmesis logo line, the one ending with '(tm)'. Note
that there is a CRLF pair on the fourth tcpdump line... :P
I believe that is because VMS is wrapping output at 80 characters, and (unfortunately)
don't realize that some characters are non-printing, as they are part of escape
sequences. So the wrapping happens, even though we're not at column 80 yet.
