esp32 does not connect via putty

[laz7591]

I'm new at esp32.
Following http://esp-idf.readthedocs.io/en/latest ... ndex.html# successfully installed Toolchain and ESP_IDF, connected ESP32 to PC (win7), port is USB-SERIAL CH340 (COM5), but running Putty and opening serial line nothing happens. Putty parameters are set up as win device mgr com port is set.
Can you help me why?

The dev board is Geekcreit® ESP32-DevKit ESP32.

Running MSYS/Mingw32 ls -l /dev/tty* comes:
crw-rw-rw- 1 Hp None 117, 5 Aug 30 18:28 /dev/ttyS5

windows com port start with COM1... COM2...COM3 and so on
/dev/tty* start with /dev/ttyS0 ... /dev/ttyS1 ... /dev/ttyS2 and so on

if you runs:

Running MSYS/Mingw32 ls -l /dev/tty* comes:
crw-rw-rw- 1 Hp None 117, 5 Aug 30 18:28 /dev/ttyS5

CH340 then is on /dev/ttyS5 right?
but you use COM5 - think this is wrong if there is CH340 from your board is on /dev/ttyS5

try putty with COM6
or try putty with /dev/ttyS5
( cygwin, mingw msys )

and you are done

best wishes
