Does anyone have any references to implementing serial communications over TCP/IP using message protocols [ASTM 1394](https://www.astm.org/e1394-97.html) or [CLSI LIS02](https://clsi.org/standards/products/automation-and-informatics/documents/lis02/) ? Any pointers/references are highly appreciated.

Hi There!

It's difficult to provide any pointers since the specification is hidden away behind a paywall. I can only assume that it's some binary encoding for data that is sent over a wire using TCP/IP.

Node-RED does have a tcp node for sending and receiving data via TCP/IP but it probably does not have anything specific for doing CLSI LIS02 since it's a closed-source paywalled specification.

Having a quick look through existing nodes though, there is, for example, the [APRS](https://flows.nodered.org/node/node-red-contrib-aprs2) node that implements the [APRS](http://www.aprs.org/) protocol. Looking at the [source code](https://github.com/ampledata/node-red-contrib-aprs), there's a nice example of sending [APRS packets over a socket](https://github.com/ampledata/node-red-contrib-aprs/blob/f364de30875bac66931a995279e9ecfd2211c95a/aprs/aprsLib.js#L335-L429).

I would assume something similar would need to be implemented for CLSI LISO2.
