Oliver Schmidt 39f83b7709 Allow Telnet65 to send ASCII code 0 - on the Apple II. ... Chris made me aware that ASCII code 0 actually is a valid character (usually entered as Ctrl-Space or Ctrl-@) and that it is actually used (i.e. by EMACS). The Apple II allows to natively enter the ASCII code 0 via Ctrl-@. However so far get_key_if_available returned 0 in accumulator to signal that no key was pressed. In order to allow the Apple II get_key_if_available to return the ASCII code 0 in the accumulator I changed it to use the carry flag to signal that no key was pressed. Because get_key_if_available needs of course to behave the same on all targets I changed the other implementations to use the carry flag too. Unfortunately I don't know enough about input capabilities of the C64 to decide on how to best get Telnet65 to send ASCII code 0 there.		2017-08-09 21:27:28 +02:00
