I have an ESP8266-based Hayes Compatible WiFi Modem, like the one sold on https://theoldnet.com/store
I mainly use it with ProComm terminal software for BBSing but I'd like to ALSO have that same WiFi modem "dial" into a fake dial-up Internet service provider and get web browsing capability within Windows 98, just as if I'd connected to a real Dial-up ISP.
Furthermore, I want to do this WITHOUT flashing the firmware on the WiFi modem to something other than the original Hayes-compatible modem firmware.
I want to be able to seamlessly hop between BBSing with ProComm and connecting to my fake ISP in Windows 98.
I've been told this is possible, likely using a Raspberry Pi as a SLIP server, but I've never been able to find a tutorial for setting this up with one of these WiFi modems. Can anyone point me in the right direction?
