To see an Ada example you just need to look at the file "g-socket.ads" 
aka "GNAT.Sockects" and instead of coping and editing the listed program 
"pingpong.adb". You can just download the text file from:

http://www.rtems.info/ftp/pub/rtems/4.8.2/ada-examples-4.8.2/pingpong/pingpong.adb


Then edit the line
       Group : constant String := "239.255.128.128";
to
       Group : constant String := "127.0.0.1";

then compile and run, if the 127.0.0.1 is setup as a local loopback.
If you examine the code you will see a few logical errors in the 
listing.


As for UART there was and might still be a UART I/O ada package 
on net or it might listed under Serial. Or you could use the Ada/C 
Serial_Port_driver in MaRTE_1.9.

Then use the serial driver to build a GPIB interface packages.
