WiFiStation: A WiFi interface to the MailStation#

This project is a set of firmware, tools, and hardware specifications for a board housing an ESP8266 module which talks to a Cidco MailStation over its parallel port.

WiFiStation acts as a modem with an AT command interface allowing the MailStation to issue AT commands to "dial" to telnet addresses rather than phone numbers. This allows the MailStation to use software like msTERM to connect to BBSes over WiFi rather than its internal modem.

All communication between the WiFiStation and the MailStation is also echoed on the WiFiStation's USB serial interface, so commands can be sent from a host computer as well.

For the latest documentation for this project, please see my WiFiStation site.

Hardware Details#

An MCP23017 MCP23S18 connects to an Adafruit Feather HUZZAH ESP8266 over I2C SPI and has 12 of its GPIO lines (8 data, 2 input status, and 2 output control) routed to pins on a DB25 connector, which plugs into the MailStation's printer port.
