Formulas
The waiting time is t × 100 ms for every macro execution.
m specifies macro executing mode when the LSB (least significant bit) m = 0
The macro executes r times continuously at the interval specified by t when the LSB (least significant bit) of
m = 1.
Exceptions
If this command is received while a macro is being defined, the macro definition is aborted and the definition is
cleared.
If the macro is not defined or if r is 0, nothing is executed.

MICR commands

MICR reading

These commands control the Magnetic Ink Character Recognition (MICR) check reader, including how it parses the
character strings on checks.
The section, MICR parsing, describes how to create a parsing format and how to create and maintain an exceptions
table.

Default:
All data returned
Reads and transmits the MICR data and adds a carriage return (0x0D). One status byte precedes the MICR characters.
If no parsing format is selected with either of the define parsing format commands (see below), all data will be
returned, which is the default.

Good read, data follows
Bad read, data follows
No check present, no data
Paper jam, no data
No MICR characters, no data
