I propose the code not using DTR.

[Hiroaki Okoshi]

Thank you for the wonderful code.
I am allowed to refer to it.
However, DTR did not exist in UB232R which I have.

It is a problem that these codes must use DTR.

RESET is controlled by RTS.
DTR does not use it.
As for the following, only an adjusting point is.

It was able to write in G13 well by UB232R.

Bye

Hello Hokoshi.

Thank You for feedback and proposal.
This is great idea to eliminate separate pin to control fixed level on TOOL0 pin. I'll implement it shortly.

Hi, rl78flash now supports mode in which Reset signal is generated by RTS pin. See -m argument (mode 3 and 4).
