i think you would need ports.e

2400baud   = speed the modems communicate
7bits      = number of bits making a transfer unit (byte)
even       = "even parity" = bitwise parity
2 stop bits= trailing bits signifying end of transfer unit (byte)

btw: this protocol setup is quite rare. the most common
is 8,n,1 which is 8bits, no parity, 1 stop bit...easier
to deal with than your 7,e,2 protocol... on the other
hand tho, with 7bit you only need to deal with the first
~128 characters in ASCII (alphabet & KB char's) and so
dumb terminals are easier to create

it indeed is... especially with that bizarre protocol...
only other times ive seen 7e2 used is for real-time control
interfacing, real old dumb terminals and certain
atm/C.Card readers approval modems dialing to the
central account database...
