and 57600 bps in addition to the default speed 9600 bps.
•
To enhance ticket handling speed, front load printers read track 2 data to
memory when loading the ticket. Previously, a separate read movement
was required when !D command read data to host computer.
•
Support for Dallas 80C320 microprocessor (on control board) introduced.
906-280
Bug fixes
•
This firmware version now supports both the old 80C32 processor, an
enhanced ("incompatible") 80C32 processor, and the enhanced 80C320
microprocessor.
•
An erroneous encoding with the !N command now results in NAK + F
(15H + 46H).
Restrictions
•
It is not possible to read track No. 2 on 110 mm long tickets inserted
through the optional front load mechanism.
•
Specifying text, graphics or bar code printing outside the valid co-
ordinates makes the processor enter a loop with strange behavior of
lamps, paper feed and cutting motors. Fortunately, you will discover this
problem already during the design and testing of the application software.
To recover from the error situation, clean the TTPM2 from any remaining
paper particles and perform a "warm start" by holding all three operator
control push buttons pressed while you power ON the unit.
•
Transmission rate 9600 baud is always used even if 19200 or 57600 baud
is selected.
906-290
Bug fixes
•
Transmission speed 19200 baud can now be selected.
Restrictions
•
Transmission rate 57600 baud cannot be selected.
