Card Reader Commands

Operational Commands

All operational commands for the magnetic/smart card
reader peripheral are IMMEDIATE commands, taking the
form of Easy Print commands (bracketed by "{" and "}") and
preceded by the ESC (1Bh) character. Responses vary by
command. All operational commands are two characters,
followed by:
! command complete, no data is expected in response
? command complete, response with data expected
: data for peripheral follows
In addition, the reader has configuration options which can
be semi--"permanently" set in Flash for LED usage, Mag-
netic Stripe and Smart Card reader. Format for these con-
figuration commands follows the self--writing three charac-
ter configuration commands (similar to IR related
configuration commands).
In all cases, the printer will respond with either a NAK
(N<crc>}, or a WACK (W<crc>) indicating the printer is
busy writing to flash followed by an ACK (A<crc>). The
CRC is the common CRC--16.
