This are the (new) Support Forums for FSUIPC and related products.

These forums replace the old support forums which have been running for 20+ years. The old forums contain a wealth of information on all FSUIPC products, and are still available (until the end of the year) for read-only here.

At the moment these new forums are quite empty – I will be updating the FAQ section and copying across the User Contributions from the old forums in the next few months.

Please note that you will need to Register and Login to post for support, and also to download attachments. You can view these forums without registering.

Support is also available via Discord. Please use the following invite link to join the FSUIPC Discord server:

Work around for UDP sockets in fsuipc5

Since LUA sockets no longer work in FSUIPC5 I came up with this work around:

First I created two virtual serial ports with this free app com0com

it creates two virtual serial ports and links them together. One port is connected to a LUA script with com read and write and the other is connected to this

free app CommTunnel. this app even has a window so you can see whats being sent and received.

I use esp8266 12f wifi chips with mcp23017 gpio expanders(I2C version) with adafruit library(for mcp23017) and arduino IDE for programming. (ordered in bulk from china they are very

cheap and you can chain 8 via I2C for 128 gpio ports on one esp12f). The 8266 is more powerful and has more memory and costs alot less than an arduino and has WIFI. you can get the

nodemcu devkit that has a serial interface on board but i am trying to cut out as many wires as possible.

[N.B. I have copied this contribution form the old SimMarket supportforums, originally posted by user brian60. Note however that stabdard lua sockets should now be working in all versions of FSUIPC]
