Furthermore, ctrl-s can cause problems if dealing with terminals
that use software flow control where ctrl-s is XOFF, saying stop
sending data until you send an XON ctrl-q.

When Radio Shack brought out the Model 12/16 it had a number of
extra keys around the numeric keypad which were set to make life
easier with Scripsit which used mnemonic ctrl sequences (e.g.
ctrl-i was insert, ctrl-d delete, etc.).  Almost immediately
after this came out with Xenix systems, people started calling to
say that their system had locked up.  They had pressed the
function key that sent ctrl-s.  Pressing ctrl-q fixed their
problems.

WordStar used both ctrl-s and ctrl-q as cursor control keys,
which of course caused problems with serial terminals.

IMHO, the most egregious demonstration of ignorance of standards
is Microsoft's use of the single ESC to cancel things as the ESC
character is supposed to start a command sequence, and is not
complete without some modifier(s).  This is why FilePro uses the
ESC-ESC sequence to execute.

When dealing with any spammer, one must always keep in mind that you
are dealing with someone who makes their living through forgery, fraud,
theft, subterfuge and obfuscation.  Stated simply, spammers lie.
