Is there an implementation for dealing with rs232 serial port ?
and where can I find it ?
Thanks in advance for Your time and considerations.
best regards,
Walter Cedric

Under what OS? On what hardware? Using OS calls? Using BIOS
calls? Using direct port IO? Using interrupts?

Sorry for the lack of precision
I am using Object Ada on a pc104 (486 sx 16 Mhz) with the free
TNT dos extender from Pharlap.

You still didn't specify the OS. Since you're using a DOS extender,
and the various flavors of Windows have their own built-in DOS
extenders, should we assume the OS is DOS?
You also did not specify whether you want to access the hardware
directly, or through OS services.

yes alright,
I am using a DOS-platteform version 3.2, it has no matter how I
would like to access com port, hardware directly or through OS
services. (the more easy is it, the best it would be)
The only parameter : it should work before next wednesday for a
robotic contest.
I am using two device(not critical) sonar ranging system and
servo control wich are using serial binding.
I must be able to read and write data on com port.

This is a matter that is highly dependent on the platform, both
hardware and Operating System.
Some questions to be answered are:
1. Are you looking to manipulate the hardware directly, e.g.,
by reading and writing values from and to registers?
Some OSs will not allow user-level code to do these
operations.
2. Are you looking to access the RS-232 port through
Operating System services -- e.g., by treating the
device as a file to which one can write, and from which one
can read?
With more details of what you're trying to accomplish, an
appropriate solution can be suggested.
I have done serial port IO on a number of platforms and OSs,
all in Ada95.
