  Heh.  This seems to be a little-known fact, but AT command strings are
alive and well.  I design telecommunications systems.  Cellular modems
use a vastly-extended version of the original AT command set to control
all functions.  By "vastly-extended" I mean the AT command set reference
manual for one of the modem modules I've designed into several products
is nearly seven hundred pages long.

  So, frighteningly enough, not only are those long textual init strings
alive and well, there's far more equipment deployed these days that use
it than there ever were back in the BBS era.
