this machine automatically selects [esc] (1bh). [lf] (0ah). [nul] (00h) or {(7bh). | (7ch).} (7dh) as an interface command control code. after the power is turned on, the program checks the data from the host for [esc] and { and assumes the data whichever has been sent first to be a control code.
for example, if [esc] is sent first after the power is turned on, [esc]. [lf]. [nul] becomes a control code, and if { is sent first, { . | . } becomes a control code. control code selection is made for every command. if the first command is [esc] ～ [lf] [nul], followed by [esc], the control code becomes [esc]. [lf]. [nul], and if it is followed by { , the control code for the next command becomes { . | . }. when { . | . } is a control code, the data of 00h to 1fh in { ～ | } is ignored.
however, the data of 00h to 1fh becomes valid while processing the graphic command or writable character command in hexadecimal mode. when { . | . } is a control code, { . | . } cannot be used in the data of the data command or display command.
(2) manual selection (esc. lf. nul)
the control code of the command is [esc] (1bh). [lf] (0ah). [nul] (00h), and the control code selection is not performed.
(3) manual selection ({ . | . })
the control code of the command is {(7bh). | (7ch).} (7dh), and the control code selection is not performed. data of 00h to 1fh is ignored and discarded in this mode. however, data of 00h to 1fh becomes valid while processing the graphic command or writable character command in hexadecimal mode. { . | . } cannot be used in the data of the data command or display command.
(4) control code (manual method)
in this method, the control code is set by the parameter setting in the system mode.
the code used in each command should not be set as a control code.
in the data command or display command, the code designated by the control code cannot be used.
