Hello you all. I am kevin and I need your assistance with a project of mine. 
Normally, through trial and error, I would find the solutions to my 
programming problems but this time I am time restricted. You see, I wish to 
send bytes of data to the stamp2( a microprocessor chip) using the keyword 
outportb. The program to send the bytes of data via the RS-232 port is 
written in C++. The program for the stamp2 which will recieve the data is 
finished and tested. I am unfamilar with it, as a matter of fact, this is 
the first time I am ever using it. I have been browsing your mail archives 
and have found some interesting stuff but not what I need. Please help me 
out as soon as possible.  Thanks.
This is the code that I have written so far:

PS: I will start trying to correct my digit. h that I will send after 
reading some of the helpful letters you have as I like to help myself. Hear 
from you soon.
