Can not connect from WSL

[horihiro]

I'm trying to use this useful tool from bash on WSL in order to write my program into ESP8266.

But the process stoped after trying to connect was displayed. Please see following result.

Isn't execution on WSL supported? Does anyone know about it?

$ ./esptool -vvv -cd nodemcu -cb 115200 -cp /dev/ttyS11 -ca 0x00000 -cf ${PATH_TO_BIN_FILE}
esptool v0.4.13 - (c) 2014 Ch. Klippel <ck@atelier-klippel.de>

trying to connect

ESP8266 is connected via COM11, so I use /dev/ttyS11 on WSL.
