MT-95 RS-232 HiCo/LoCo Encoder/Reader
30
<ES> is the End Sentinel for each track encoded. The End Sentinel is a
question mark (?) for all three tracks. This must end each set of
track data.
<ETX> is the End of Text character (0x03), or control C on the keyboard).
When this character is received by the encoder, it will switch to the
encode mode until either a successful encode or an abort character
is received.
<CR> Carriage Return (0x0D)
<LF> Line Feed (0x0A)
<SP> Space (0x02)
PC ENCODED EXAMPLE
To encode “ABCDEFG” on Track 1 and “123456789=112233” on Track 2 and keep Track 3 the
same, the data to the encoder is:
<STX>%ABCDEFG?;123456789=112233?<ETX>
The STX character shows on the computer’s screen as a happy face (on some systems it might
appear as $02). The ETX character shows on the computer’s screen as a heart (on some systems
it might appear as $03). It is not necessary to send a carriage return after the ETX. With this
command, Tracks 1 and 2 will be encoded. Track 3 will be left as it is.
ONLINE COMMANDS
The following notes apply to Online Commands:
1. All commands begin with a forward slash “/” (0x2F) which is followed by one or more
characters (case insensitive). The command is executed upon receipt of the last character.
2.
The response to the messages is an ACK message. This message has the following
format:
<STX><ACK><ETX>
(0x02 0x06 0x03.)
3. If an illegal command is sent, the response will be
<STX><NAK><ETX>
(0x02 0x15 0x03.)
