Okay folks, I think I just got a
clue about how to open a serial (com) port in Rebol. I need to open up a
serial port for a web cam device I am messing around with. It is
programmable, so it will accept VISCA commands - if I can find a way to insert
the data to the port. Okay, so I don't know if this is the complete
answer, but I have been fooling around with opening up com1 or lpt1. I am
here trying to understand the command strategy and after a few tries, I decided
to try the direct approach. I looked something like this
com: open/binary/direct
%com1
When I hit <Enter>, I didn't
get the standard error message - as if something had been opened for
input. I don't have anything on com1 with the computer I use at home so I
try something a little more obvious.
com: open/binary/direct
%lpt1
To open up %lpt1 for input.
There was no response again, but no error message! So I tried to insert a
text line to the input field and I got some response from my printer! Now,
it didn't print anything, but I obviously have struck something that is a
definite hint! It seems that Carl Sassenrath has made it too simple.
Anyway, there it is. I would like to see you all complete the equation for
smooth communication via a com port. Good Luck.
