The ESP8266/ESP32 comes with modem simulator firmware, but it's confusing, verbose, and lacks a lot of the features that would make the ESP really look like a modem to a client computer. This project attempt to fix all those flaws with a custom Arduino implementation of that software.

Features

Supports multiple independent client connections
Includes "Stream Mode" client with TELNET codes
Supports PETSCII translation in Stream Mode
Supports all standard Hayes commands
Supports XON/XOFF flow control.
ESP32 Supports SD-card and X-Modem/Z-Modem
Supports NTP (Time) client to check the time.
