used as single entry one's.
It is now possible to suspend operation after magnetic encoding by inserting a ~
character in the !M data string.
A bug in the error handling of command !T has been corrected. Sensors in the
upper and lower entry are used to verify that the ticket the upper rear entry is
backed out enough when using lower entry.
Now it is possible to send uneven No of characters for Code 2-of-5.

Improvements:
Delay when starting front motor after cut removed. This timeout caused problems
on some printers where the front motor did not start immediately, causing a shift in
print position.
Removing paper when loading now releases the feed solenoid. Paper out when
sending !P results in the printer sending NAK + P and ignoring the P command.
New stepping-sequence when reversing feed.
Extended reset is now default.
Startup behavior in dual track mode corrected when only upper track inserted.
New cleaning routine that operates both motors if powered up with yellow button
pressed. Also allows setting of burn time using buttons.
Speed improved when building the ticket image.
Problem fixed which could cause trailing ticket to be fed to long after cutter.
Extra reverse when positioning ticket removed. Activation of solenoid delayed to
prevent it from being actuated during normal positioning.
!O n implemented. n=1 results in 512 bits read from track 1. . n=3 results in 512
bits read from track 3. Any other value including none gives the standard !O reply.
Both encode and print speed can be set. The third parameter decides what motor
to address:
!C<CR><LF>
!F A E 30 250 1 "Encode speed (full-step)"<CR><LF>
!F A E 30 190 2 "Print speed (half-step)"<CR><LF>
!P<CR><LF>
Known bugs:
Encoding attribute { does not work on track 1. Use lower case d instead.
4.70
PIO Timing changed back to slow because of chip tolerances caused unpredictable
behavior
The possibility to reset after a critical error has been removed because it caused
problems when printing many small bitmaps.
When reading track 3, the string was only terminated with an LF. This is now
corrected to CR/LF as it is on the other tracks.
Stepper motor for encoding now runs half-steps instead of full steps. This gives a
smoother ride and improves encoding reliability.
