yes - 4 high speed lines all locked at 38400 on a
dumb multiport board will load the system -

we at one time used all dumb serial ports - but about a year ago
we installed intelligent boards - along with more high speed modems -

and will all the modems going wide open (with zmodem transfers at high speeds)
the system is so fast it can't be noticed!
