shell/telnetd/SpaceWire question

Ah, yes, that makes much sense; I guess I was
focused on the "packet" nature of SpaceWire, but it
does look more like a serial port...

So I wonder - is using telnetd completely wrong
thinking on my part?
Maybe I should look into something that would be
used like this:

     "/dev/ptySpaceWire",    // SpaceWire
pseudo-terminal device

If so, where do I begin to create the
"/dev/ptySpaceWire" device?  I highly suspect this
is so obvious to more thoroughly schooled Linux
