You need to disassemble the code fragment which you are debugging and
glean the info from there.

GDB and Bash both use termios, which writes to the console via Int 29h.
I have on my (infinite) todo list to add some facility to force termios
to use DOS I/O, or change termios to always use DOS I/O when the
terminal is in text mode.  Volunteers are welcome to work on that ;-)

Another idea is to add the dribble functionality to GDB.
