 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

Here's an ESP32-C3Supermini flashed with Annex receiving serial messages from the PC and sending the message along to the PC via UDP, and also receiving UDP messages from the PC and passing them along to the PC via serial:  ' passthru.bas port=54321 serial2.mode 9600,8,7 udp.begin port onUDP UDPRx onSerial2 SerRx wait UDPRx: pause 500 msg$=udp.read$ udp.reply "ACK "+msg$ ' optional reply print2 msg$ wlog "UDP msg: "+msg$ return SerRx: pause 500 ' allow time for Rx to arrive msg$=serial2.input$ if msg$<>"" then udp.write "192.168.2.237", port, msg$ wlog "serial msg: "+msg$ endif return On the PC, the lower right window is TeraTerm, from which serial data is sent to and received from the ESP. The upper right window shows the command for sending a UDP message from the "DOS prompt". The middle right window shows a "DOS" UDP listener. The PC is a stand-in for a PicoMite or CMM2 or any other micro which does not have net connectivity. The UDP sender optionally gets an "ACK" back. The serial sender could also (but doesn't in this program). SERIAL2 is used instead of SERIAL so that system messages are not injected. Of course, there is a world of additional things Annex can do for that device (including telling it what the date and time is.)
