Serial I/O Help?
Could someone please suggest a reference to me for serial communications on
the Amiga?
I have an A3000 with a 2232 multi-serial card. I am interested in sending
and receiving messages through the serial port(s) under ARexx control. I
have had limited sucess so far in sending info but not in receiving it.
The problem is I don't know the basic methodology that the Amiga OS uses to
handle serial communications. So I am basically floundering around in the
dark. Once in awhile I get something right but I don't know why.
Aside from needing to know the basic structure of the serial handling in
the Amiga, what I really need to find out is how to capture responses from
serial devices. I have a plotter that can be queried for various info (pen
location etc.). I have sucessufully issued commands from an Arexx script
to draw lines etc. but when I give it a command that requests information I
don't know how to capture the return answer data.
Any Help, suggestions, or comments would be appreciated.
