There are two drivers that use VSCP tcp/ip link protocol vscpd <-> vscpd or oyther device with VSCP tcp/ip link interface and VSCP tcp/ip link server. vscpd <-> clients |

If you want to connect manually yes telnet is right. The VSCP driver connects to a MQTT server. This is how all drivers connect nowadays. In the past all drivers was talking to each other inside the vscpd server. Now this can be accomplish by using the same topic on an MQTT server. |

Sorry i meant 9598 is used by VSCP tcp/ip link protocol. 1883 is MQTT. The mosquitto test server has a good list of MQTT standard ports used. As you see 12883 is usually used for unencrypted traffic. |

yes, c/c++ or python and node.js. It is just a c-lib so easy to port to other languages. It handles the VSCP tcp/ip link protocol and contains a lot of other helpers. Docs are here |

Thats for the MQTT driver. No need for it today. Settings are here https://github.com/grodansparadis/vscpl2drv-tcpipsrv and is the same as for the daemon config file https://grodansparadis.github.io/vscp/#/configuring_the_vscp_daemon?id=config-mqtt |
