malfunction consequently. In order to prevent this buffer overflow, Parani-BCD110V3 works as
follows.
When using hardware flow control, Parani-BCD110V3 disables RTS so that it stops receiving any
further data from the host when the buffer becomes full. RTS will be re-enabled again to begin
receiving data from the host when the buffer has created more room for more data.
When hardware flow control is not being used, the Parani-BCD110V3 clears the buffer to secure
room for the next data when the buffer becomes full. This can mean a loss of data may occur.
As the transmission data becomes large, the possibility of data loss becomes greater.
For large data transmissions, the use of hardware flow control is highly recommended. (Not
support flow control in Multi-Drop Mode.)
3.5. Remote Configuration Mode
The Parani-BCD110V3 supports remote configuration mode. After connecting the Parani-
BCD110V3 through Bluetooth, send three remote escape sequence character (default: ‘-‘, 45) for
remote configuration mode. Then, the Parani-BCD110V3 will enter remote configuration mode.
You have to enter the password with “AT+PASS” command. The default password is “0000”.
After the password authentication, the remote configuration of the Parani-BCD110V3 is available
with the “Remote Configuration Enabled” message displayed. After password authentication fails
three times, remote configuration mode will close. If there is no input for two minutes after entering
remote configuration mode, remote configuration mode will also close.
The password for remote configuration mode is configurable using “AT+CHPASS” command. Its
maximum length is 8. If it is not set, remote configuration mode is not available.
AT+CHPASS=<values><CR>
* AT commands such as “ATH”, “ATO”, “ATD”, “AT+BTSCAN”, “AT+BTINQ?”, “AT+BTCANCEL”,
“AT+IOCONNECT”, “AT+IODISCONNECT”, “AT+SCOCONNECT”, “AT+SCODISCONNECT” are
not performed at remote configuration mode.
