GNAT.Serial_Communications ?

GNAT.Serial_Communications ?

[Tomek Walkuski]

Hi group,

I want to communicate with serial port in Ada. What is the best choice
in your opinion? GNAT.Serial_Communications? Where can I find any
documentation about this (GCC GNAT Reference Manual says nothing about
this)?

Did you try the GCC GNAT User's Guide or read the self-documented code
package GNAT.Serial_Communications?

I've gnat-gcc-4.3.0 (Fedora 9) and I don't have g-sercom.ads under /
usr/lib/gcc/i386-redhat-linux/4.3.0/adainclude .

Am I something missing?

No Error!  The standard GNAT system does not come with a Serial or UART 
package.  The package tree is a new addition (April 2008) so the 
maintainers may not have this package yet or they may not include it 
because it not apart of the Ada RM.

It might be included in June version of the GNAT-2008 package, but for 
GNAT-2007 you will need to do a search and down load the set of files 
that makes this package.

Note: you can find a copy of the serial communication package tree at:
    http://gcc.gnu.org/viewcvs?view=rev&revision=134003

Then compile the set of files manually to create the serial communation 
package. Now, you can either just copy and use then when you need this 
package.  

Note: If you know what your doing you can add the source and "*.ali" to 
your GNAT system adainclude/adalib directories and the object files to 
the "gnatlib" file.

I have got GNAT.Serial_Communications sources from GCC CVS, renamed
packages and I am trying to compile:

gcc -c serial_com.adb
serial_com.adb:40:06: warning: "System.Crtl" is an internal GNAT unit
serial_com.adb:40:06: warning: use of this unit is non-portable and
version-dependent

You can't just do that and expect to work, as this unit depends on
other runtime library changes. For example, the "close" function in
System.Crtl was added on March 26th and is needed by
GNAT.Serial_Communications.

If you need this unit, you should either wait for the next release or
build a new compiler and runtime libraries.

Hello,

I am learning Ada and I find it quite funny that this serial stuff
happens as COM ports are no more available on the machines...

Am I right spending my time trying to learn this language or is it
like latin (good to know some sentences to shine at tea time) ?

I don't appreciate tea too much...

It depends.  On the low-end motherboards and stocked computer system the 
uarts have been removed, or you could say replaced by the usb ports.  But 
most other motherboards and some server still have them.  Plus you can 
always add a uart card to any computer.

Ada is not a special-purpose language that can only do serial port
communications. You will benefit from learning Ada for any kind of
programming. Multi-tasking, database interfaces, networking, graphical
interfaces, embedded progamming, etc; Ada supports them all.

I use serial ports on a daily basis through USB to serial interfaces
on my desktop machine and my laptop. Many embedded systems still use
RS232 for communication. And the way to configure those serial USB
ports is similar to the way to configure vanilla serial ports.

However, if you're trying to learn Ada, using the serial port is
probably not the best way to dig into the language :)

OK, OK... ;-)

I was just kidding... It's alive !
ThanX for the answers.
