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.
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.
The full BOM can be found here.
