Definable area: a = 01h:
Function:
The following data is transmitted from the RS-232 interface:
This command is valid in both User setup mode and Normal mode.
Definable area: 00h ≤ a ≤ 0Bh
Function:
Operation is [DTR=MARK][Communication settings change][DTR=SPACE], so do not send the next
data until DTR=SPACE.
If unsent data is in the transmit buffer (due to DSR=MARK), this data may not be transmitted
correctly, so ensure the transmit buffer is clear before issuing this command.
For baud rate setting a = 07h – 0Bh, display operation is not guaranteed. Do not use this setting.
Definable area: m = D0h
Function:
Memory re-write mode is used for changing the firmware and fonts, etc in FROM that cannot be
changed in User setup mode.
Changing this FROM requires special commands and tools.
Do not use this command.
