Try:

  sim> set baci debug
  sim> set console debug=baci.log

If you examine the debug trace after doing a CTRL+O in EDIT, you'll see 
that the CTRL+O is received from the Telnet connection twice: once when you 
enter it as a command, and a second time in response to the "ESC d" (block 
transfer request) sent by EDIT to read the screen.  In other words, it's 
being sent as part of the data read from the screen, which is how it winds 
up in the file text.  The CTRL+O is actually embedded wherever the cursor  
position is when you enter it.

I think that's a bug in QCTerm; the CTRL+O is being stored as part of the 
screen buffer when you type it.  A real 2645 terminal stored typed control 
characters in the screen buffer only when "display functions" was on.

(The same CTRL+O behavior is observed on the forthcoming 8-channel 
multiplexer simulation.)
