9. ERROR HANDLING
9.1 Magnetic Card Read Errors
9.2 Communication Errors
9.3 Power Failure
<Calculating Procedure of checksums>
If a card read is bad no data (Tx:error.<sh><sl><CR><LF>) will be returned when track data
is requested with the T1,T2,T3, or TA commands.
If AutoClear = 0 when the :SR command will return the status of the most recent card swipe.
The status return string contains data on Missing STX, ETX, and LRC errors for each track.
Please see the details of the :SR command in the preceding section
The UCIMAG will acknowledge most RS232 commands with <CR>.
Please see preceding section for details. If the UCIMAG fails to receive the command correctly
it will not respond. The Host PC control software should assume that if no response is received
in 1 second a communication error has occurred and the command should be resent.
If power fails and is then restored, the unit is reset and reinitialized. On reset the UCIMAG will
send the current firmware revision. In this way a host PC can tell when power has been lost
on the UCIMAG.
Example) In case that a return data is “SE:400000030000”.

100h-19h = E7h (E7 is the two’s complement value of 19h.)
