13.3.42 Read Status information
Code:
1Fh 28h 65h 40h a [ b c d e ]
Definable area: a =2 (02h), 32 (20h), 48 (30h), 128 (80h)
a= 02h : Firmware version information (b, c, d, e are not used)
a= 20h : Memory checksum information
0000h ≦ ( b + c x 100h ) ≦ FFFFh : Start address
0000h ≦ ( d + e x 100h ) ≦ FFFFh : Data length
a= 30h : Product type information (b, c, d, e are not used)
a= 80h : User font information (c, d, e are not used)
20h ≦ b ≦ FFh ：Character code
Function: Respond with the requested display status information.
The following data are sent from Asynchronous serial interface
This command is only valid in Serial OUT mode.

13.3.43 Display Status information
Code:
1Fh 28h 65h 41h a
Definable area: a =2 (02h), 32 (20h), 33 (21h)
a= 02h : Firmware version
a= 20h : Firmware checksum
a= 30h : User font table checksum
［P(20h-1)…P(FFh-5)］
Function: Display on home position the requested status information.
This command is only valid in user setup mode.
13.3.44 Serial OUT mode start
Code:
1Fh 28h 65h 83h d1 d2
Definable area: d1 = 49h （Character "I"）
d2 = 4Eh （Character "N"）
Function: Switch SBUSY to Serial OUT and start “Serial OUT mode”.
This command is only valid when Asynchronous serial interface is selected and
mode is Direct Command mode.
Display screen is cleared and normal commands stop being accepted.
Wait at least 5ms after sending 4Eh ("N") before sending next data.
During Serial OUT mode, do not use SBUSY for communication flow control.
