I posted a small TCP (and I suspect UDP) example a while ago, that works for me.
Assuming that the old 'legacy' daytime stream server runs on tcp port 13 (as an example).
$ gst daytime.st
Loading package ObjectDumper
Loading package Sockets
'Sat Jun 6 10:30:16 2020'
As Derek indicated last june, the key issue is the namespace support.
The class below is Sockets.Socket where Sockets. is the package name and Socket the class name:
$ cat daytime.st
Eval [
PackageLoader fileInPackage: 'Sockets'.
s _ Sockets.Socket remote:(Sockets.SocketAddress createLoopbackHost) port:13.
(s upTo: Character cr) printNl.
s close.
