IBM 3270 emulation options

Numeric check

This option specifies what type of numeric checking should be done by the emulator when the host defines an unprotected field as being numeric. There are four possible values that can be set:

`None`	No numeric checking is done. This is equivalent to a Typewriter keyboard selection in some emulators.
`Strict`	Numeric checking is enforced, and only numeric digits, decimal point, comma and minus sign may be entered in the unprotected field.
`Emulator`	Same as above but also allows plus sign (this is the numeric checking that is implemented in several other emulators).
`Relaxed`	Allows all of the above, also uppercase letters and shifted numerics (for example "!" and "#"). This is equivalent to a Data Entry keyboard selection in some other emulators.

The default setting is None, i.e. numeric checking is not performed.

Treat line as error message line

Text from the host at the line specified will be regarded as an error text and will be displayed at the status line together with a notification sound. Text starting after position 10 at this line will not be regarded as an error text.

Mute host alarm

Ignore alarms issued by the host application (The volume control and alarm sound is configured in the iOS/Android Settings).

Mute key input alarm

Ignore key input error alarms (The volume control and alarm sound is configured in the iOS/Android Settings).

Allow cursor in protected area

Normally if you point outside an input field, the cursor is not moved to this location. Instead the keyboard, if displayed, is hidden (removed). If this option is checked, the cursor is instead moved to the protected location without changing the keyboard state.
