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, Magnetic Stripe and Smart Card reader. Format for these configuration commands follows the self-writing three character 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.

General Reader Operational Commands

The card reader has two LEDS, red and green that may be used to give a visual status to the user for either magnetic cards or smart cards. In addition, the printer can be polled for general card reader status as well as the current state of the LEDs. Semicolons separate elements of the returned status:

Command: {RS?}
