TinyTERM supports both USB and Bluetooth keyboards. This includes all alphanumeric keys, as well as symbols, arrows, tab, return and delete keys.
TinyTERM will also accept any device that uses the Bluetooth HID profile as a keyboard. This normally includes keyboards and barcode scanners, but can also include other devices. If in doubt, check with your Android device manufacturer to determine which HID peripherals are supported.
On Chromebook and Chromebox devices, TinyTERM Enterprise starts full screen. This allows TinyTERM to use all function keys on the hardware keyboard. TinyTERM can be run in a window instead, in which case it runs in portrait mode. But some function keys will be unavailable, as Chrome OS will take them over for its own internal functions.
