Thanks for the links, Louis :-) While the price could be a lot lower, the
https://www.cbmstuff.com/proddetail.php?prod=WiModem232 https://www.cbmstuff.com/proddetail.php?prod=WiModem232&review=all mentioned on one of the pages is pretty similar to what I had in mind: some WiFi controller plus a RS232 level shifter plus good firmware = fake WiFi dial-up modem :-) AND it has everything pre-installed, with WPS quick setup. There seem to be several websites about tinkering with for example a Raspberry Pi and USB serial port adapter, using the tcpser software. One randome exammple for that: https://www.insentricity.com/a.cl/215/putting-your-retro-computer-on-the-line The WiFi232 page http://biosrhythm.com/?page_id=1453 says it is sold out - the concept seems a lot like WiModem232, but with a more bulky non-SMD circuit board for WiFi232. As WiFi232 is ESP8266 based: Arduino-Raspberry-et-al Stores sell you stuff like Waveshare RS232 (SUBD9, header, SP3232E) for 5 Euro and ESP8266 or ESP32 modules on boards with pin headers for 5 to 10 Euro (NodeMCU v2 with Lua, "ESP-01S" or Olimex MOD-WIFI-ESP8266, Olimex ESP32-DevKit-LiPo, NodeMCU-32S or similar) you could easily roll your own if you have access to the right firmware: Some jumper wires or a breadboard can link both ingredients and the ESP32 or ESP8288 listed above have micro USB sockets for power and for uploading firmware. That lets you BUILD a WiFi RS232 modem for less than 20 USD, not counting cables and case. Without even having to solder! As long as software is made? Arduino does support ESP chips.
