Much improved MODEM mode screen - it will now show wifi/call status icons, IP address, and byte count sent/recv'd

v2.09 firmware

Improvements around incoming telnet connections (thanks tynbendad!)

v2.08 firmware

Added OTA firmware update support. Firmware version check is performed automatically after wifi connects. If an update is available you can issue the command ATFU to download and apply the update.

v2.07 firmware

After establishing a wifi connection, the WiRSa device will now check for any available firmware updates available under github releases. Firmware update is not automatic - just prints a message over serial. Future update may include OTA firmware updates.

v2.06 firmware

Improved responsiveness due to display delays - now when connected to a remote system, internal display will only refresh when it has a new full screen of characters. Refreshing the display for every character received was slowing down the whole device.

When in a call, the back button will now end the call. A second back button push will exit modem mode.
