<callout color="orangered" icon="fa fa-comment" title="Description">
----
The ''USBAUTORCV'' command receives an object transmitted by another calculator using the USB link, provided the connection has been successufully negotiated. Since by default object reception happens automatically without an explicit use of ''USBAUTORCV'', the pre-condition for usage of ''USBAUTORCV'' is the disabling of automatic reception by setting flag [[manual:appendix:flags#flag-47|-47]].

If the transfer succeeds ''USBAUTORECV'' will be automatically ''[[manual:chapter6:operators:cmd_ovr_xeq|XEQ]]''ted - see ''[[manual:chapter6:usb:cmd_usbrecv|USBRECV]]'' if this feature is not desired.

To signal the user of an incoming object waiting to be received an **RX** indicator is displayed in the status area. If there's no data incoming ''USBAUTORCV'' silently terminate itself.
