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,

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.

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

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.

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.

Good Job !
Thanks a lot ! That's exactly what I search...

Hi - just came across it:

<<
DOS I/O port access

A package specification for accessing the I/O ports under DOS with implementations
for either GNAT 3.07/3.10 for DOS or ObjectAda with the TNT DOS Extender.
                                     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

If the answer is Windows NT, then please go to http://www.deja.com and
search through past posings in this newsgroup. This question has come up
before for NT at least twice.

The previous mail from Gauthier is good, but the implementation
found can only write a byte on serial port.
Is there any other ready to use solution using a real serial
transfer (baud rate, parity ....) under dos in ada using tnt dos
extender from pharlap on PC (with or without call to OS) ???????

Again a quick web surfing... Maybe the serial I/O is among the Win32
subset of TNT ? http://www.pds-site.com/Pharlap/faqtntrd.htm

In that case the Win32 code for serial port here could be useful
  http://www.usafa.af.mil/dfcs/bios/mcc_html/ada_stuff.html

BTW the famous Ralf Brown DOS Interrupt List has a chapter about Serial I/O
  http://www.ctyme.com/intr/cat-038.htm

Just "brainstorming"...
