Modem Capacity of 386's?

[Dave Hughes]

 I am looking for some good guesses. If you were to pluck out of
the air the number of 1200 baud modem-connected users a 16mhz
386 running Sco Xenix 386 with 28mls disk drives and intelligent
com boards (I am using Computone presently) would support
satisfactorily, what would you say? 16,24,32? 
 Users only readng/writing to disk running either e-mail, foxbase
like data base programs, conferencing software. No development
work or compiling.
  I am just trying to get a couple judgements as to just about where
would a 16mhz 386 begin to degrade from such uses. (I would guess
about 6 users on a similar 286)
