6.3.3.9. READER _CONTROL_CONTACT_SLOT
This Escape command is supported through the READER_GENERIC_ESCAPE message.
This command can be used to disable the contact slot until it is re-enabled through the same
command or until the reader is re-plugged. When a dual interface card is placed in the contact
slot it will get detected in both “contact” and “contactless” mode. To enable applications to
actively switch the detection from contact-only mode to contactless-only mode this Escape
command can be used along with CNTLESS_ SWITCH_RF_ON_OFF.
