   Amid all this praise being heaped upon the Supramodem, a lone voice
speaks out...

   The Supra 2400 baud modem answers with a 2250 Hz tone (for the 1200
baud fallback), instead of the correct 2225 Hz.  These tones are supposed
to be accurate to within some small fraction of a percent, which this
gross error is several hundred times larger than.  The net result is that
if the Supra is called by some 1200 baud modems (like MINE), a connection
cannot be established.  Of course I did this research since my modem would
not connect to any Supra based BBS's in town.  The attractive pricing
of the Supra seemed to outweigh any quality considerations when the BBS
operators were purchasing.  Needless to say, I do not frequent these
boards.  Our own club's board runs a 2400 baud Promethious(sp?) modem
which I have no trouble with.

   Note that if you are the Supra modem owner, you will have no trouble
at all, unless someone wants to connect to you.

   All this is not really Supra's fault, the chip set being used has
a design flaw (shall we call it a mistake?)
