Request: UART terminal for devices with keyboards (cardputer, t-pager) to add flipper functionality to control other modules

[detonation]

Describe the solution you'd like

Adding a UART mode, similar to Flipper, to control devices over UART. Devices that are currently supported like the Cardputer and now the Lilygo T-Pager (which you recently added support for) would make this far more useful than any flipper implementation.

Adding a serial terminal would allow the ability to control other esp32 modules running what I'm excited about, ESP32-BusPirate port, Marauder, and Ghost-ESP.

While the Flipper UART control mode uses a gui/buttons to send commands over UART, devices like the T-Pager and Cardputer can be stand alone serial terminals with keyboards and color screens, making it arguably far more useful.

You support a UART mode to accept serial commands, adding a uart terminal mode to SEND commands would open up a lot of useful things, especially paired with a cheap $2 esp32 module running BusPirate for advanced hardware interfacing/gpio control, for wifi and bluetooth exploration and techniques that require more than one interface, and hopefully some interesting firmwares now that we have access to C6 for Matter/Thread/Zigbee over Uart as well now.

I realize the T-Pager has a lot of bugs as of the latest firmware, but you really are one of the only softwares available for the T-Pager. I think the list is Launcher, Meshtastic UI Alpha, and Bruce.

Please can you eloborate on these bugs in a separate issue, I ported Bruce to the T-LoRa-Pager and I am not aware of any bugs. There is lack of NFC and audio at the moment but everything else shouuld be working.

First of, thanks for porting bruce to the Pager, its awesome :)

I have found multiple issues: The enter key is assigned to "!!", "&" on the second keyboard layer. Due to this you can't run commands over ssh. Backspace does not work in ssh and usb/bt keyboard tools. No way to go back to main menu from ssh and usb/bt keyboard tools.

Exiting the RF spectrogram in inconsistent and does not always work.

If you rotate the scroll wheel while in the spectrum view you can no longer exit, there is no visible menu but until you scroll back to an invisible "exit option" the exit button does not function.

I have experienced multiple cases of the screen freezing, have not yet found how to reproduce it.
