A quick check of an ASCII chart reveals that 0x12 is NOT the XON code.
XON and XOFF are (respectively) 0x11 (^Q) and 0x13 (^S).  The 0x12 code
has the name DC2 in the ASCII chart.  Regardless, why would the BBS be
telling me XON in the first place?  It never told me to stop (XOFF).

If my memory serves me well, the DC1-4 codes were originally intended
to be device-specific control codes, hence "DCx" (Device Control).
Further, I seem to remember (from Teletype days) that two of the DC
functions were "PUNCH ON" and "PUNCH OFF".

Anyway, back to the original question.  Why is the BBS sending the
0x12?
