I am noticing something odd in SimH when sending a

I can't confirm that this is not the behavior that I would experience on
the real thing.
As others have commented this is a telnet thing. You can disable telnet and
get a raw connection.
For console I use
set console telnet=2222;notelnet
set tto 8b
For other port I use
att ttix 2222;notelnet
set ttox 8b
