NUMBER Command
The number of stored identifications can be checked by the PC sending the ASCII
character N to the TIRIS reader. It causes the TIRIS reader to transmit the ASCII
character N, space, the number of identifications stored in the memory in hexa-
decimal format, carriage return and line feed via the interface.
Example:
PC --> Reader:
N
Reader --> PC: (909

LINE Function
The ASCII character L switches the TIRIS reader into a special continuous readout
mode. In this mode each correct identification causes the direct transmission of the
ASCII character L, the transponder type character, space, application code,
space, identification code, carriage return and line feed without buffer compari-
son.
If no identification is received or if the identification is not valid, the ASCII character
L together with an optional I, carriage return and line feed are transmitted.
