ViewML Industrial Browser for iOS supports both dock and Bluetooth keyboards. This
includes all alphanumeric keys, as well as symbols, tab,
return and delete keys. TinyTERM also allows use of
arrow, control and function keys from most external keyboards. And the
keyboard can even be remapped!
Option Keys
iOS reserves some keys for its own use. As a result, the top row of keys
on a typical external keyboard — esc and function keys — are not
available to TinyTERM. Neither are the fn, control or command keys. Instead,
TinyTERM uses the option key to access special terminal keys.
External Keyboard Supplements
For external keyboards that don't support the option key, TinyTERM allows you to
create new layouts specifically for use with external keyboards. They can be
created the same way as other keyboard
layouts.
Remapping External Keyboards
The external keyboard can be reprogrammed by editing a Unicode file to change
the assigned values. You can download a copy of the necessary
external.ttcodepage file here.
