Wi-Fi Modem Configurations
Default: As per block diagram
Standalone: Power jack provided for +3.7V to +16V to use the MicroView and RN-XV on their own
Interfacing: Remove RN-XV Wifly and use MicroView’s GPIO to interface C64 to outside world (analog input, PWM output, digital I/O and I²C) – all pins broken out along top of board

Firmware - Two Options
“Menu” Firmware: Simple Menu-driven interface
Dial Out (to a BBS or Telnet Host i.e. Linux)
Receive Incoming “calls”
Configuration of SSID and misc. options through interactive prompts

Firmware - Two Options
“Hayes” Firmware: Emulates a Hayes-compatible modem with AT commands,
+++, etc.
Dial Out with ATDT
Receive Incoming “calls” (potentially run a BBS) Sends RING Auto-answers or waits for ATA
Configuration of SSID and misc. options through extended Hayes commands i.e. AT&SSID=

Firmware - Two Options
Features common to both: Autostart option: Will automatically connect to a given
host i.e. CommodoreServer when powered on
Phone book (stored in EEPROM)
Configuration (stored in EEPROM)
Automatic baud detection at startup
ASCII and PETSCII Support
