Is there anyway to get Zmodem like DSZ or PD Zmodem to d/l a file using "RAW"?
I have a Door that can D/L files but won't work unless I connect to the BBS using "RAW"
Was wondering if it was possible.

It may be possible. You would want something to launch before your door, to put the telnet session in to binary mode, and then turn it off when
the door exits.
The protocol is here: https://www.rfc-editor.org/rfc/rfc856.txt
How to do it, I'm not sure, but a door author could write a door to do
it, so when you launch your door, it goes: bbs-> binary mode door ->
game -> undo binary mode door -> bbs

Ahh, OK. So you need a shim of sorts? IE: Something to absorb 0xff and escape it (and doing the telnet binary mode thing)...How to do it, I'm not sure, but a door author could write a door to do it, so when you launch your door, it goes: bbs-> binary mode door -> game

Telnet binary mode is not the same thing as Raw TCP. In Telnet binary mode you still have to escape the IAC (0xFF) characters, but not in Raw TCP mode.

Thus, not an easy workaround..?

Simply absorbing 0xff wouldn't be enough either as there are a variable number of bytes that follow the 0xff that constitute the Telnet command(s).

Right, which is why the shim would need to escape it before sending it
on. In a binary file transfer, its not an IAC command.
a 'real' telnetd will continue interpreting telnet negotiations even during a zmodem transfer. the telnetd doesn't even know zmodem is running.
