612NN Select Error Correcting Protocol Timeout
Command #612NN selects the timeout interval for ECP. This timeout applies to the
transmission of tag, report, and error messages and to the receipt of host commands.
The transmit timeout is initiated immediately after the end-of-message sequence CR/
LF is transmitted. If the host does not acknowledge the message within the specified
interval, the reader times out and retransmits the message.

interval, the reader times out and retransmits the message.
The receive timeout is initiated upon receipt of the start-of-message character (#). If
the end-of-message character (CR) is not received within the specified interval, the
reader discards the partially received message and resets its receiver.
