After using several different communication packages on the market; I have
decided to write my own because not all of them do what I want.

I have decided to write it in either Turbo Pascal, or Lattice C.  My main
problem right now is sending and receiving data from the com1: port.  I 
have only played around with it in Turbo Pascal, and can send data ok (I
think) to the port, but how can I tell if there is data 'waiting' in the
port to print?
I cant do a read from the port to check; otherwise it will just sit there
and wait for data to come in.  What I would like to know is how to do
some sort of a status on the port.  Can anyone help me?

Please send responses via mail.

Thanks in advance,
