I have attached a DS1307 temperature sensor to the D3 pin of my Wemos D1 Mini Lite. It was the only pin left. Works fine, except when I use putty.exe - serial to connect to my USB com port: then the getDeviceCount() returns 0. When I use the Serial Monitor of the Arduino IDE, it works fine.
I expect this to be related to flow control using RTS/CTS and/or DTR/DSR when I look at the schematic, but how can I tweak putty to behave like the Arduino IDE Serial Monitor does? Thx in advance!
