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. ] ----- Op 5 jan 2021 om 20:06 schreef Gary Highberger gary.highber...@gmail.com: > Hi Paolo, > > Thank you for the link. Im studying it now. Hmm.
