Table 377. UART ISP Echo command
The host should send the data only after receiving the CMD_SUCCESS return code. The
host should send the check-sum after transmitting 20 UU-encoded lines. The checksum is
generated by adding raw data (before UU-encoding) bytes and is reset after transmitting
20 UU-encoded lines. The length of any UU-encoded line should not exceed
61 characters (bytes) i.e. it can hold 45 data bytes. When the data fits in less then
20 UU-encoded lines then the check-sum should be of the actual number of bytes sent.
The ISP command handler compares it with the check-sum of the received bytes. If the
check-sum matches, the ISP command handler responds with "OK<CR><LF>" to

U
Unlock code: 23130
CMD_SUCCESS |
INVALID_CODE |
PARAM_ERROR
This command is used to unlock Flash Write, Erase, and Go commands.
"U 23130<CR><LF>" unlocks the Flash Write/Erase & Go commands.
B
Baud Rate: 9600 | 19200 | 38400 | 57600 | 115200
Stop bit: 1 | 2
CMD_SUCCESS |
INVALID_BAUD_RATE |
INVALID_STOP_BIT |
PARAM_ERROR
This command is used to change the baud rate. The new baud rate is effective
after the command handler sends the CMD_SUCCESS return code.
"B 57600 1<CR><LF>" sets the serial port to baud rate 57600 bps and 1 stop bit.
A
Setting: ON = 1 | OFF = 0
CMD_SUCCESS |
PARAM_ERROR
The default setting for echo command is ON. When ON the ISP command handler
sends the received serial data back to the host.
"A 0<CR><LF>" turns echo off.
