	Hello, I've been using Visual Micro addin for VS2015 and I noticed a slight issue with my NodeMCU. When I use Visual Micro serial monitor, it prevents the ESP8266 from resetting itself, which means it will execute its program once, reset and stop. If I use the Arduino serial monitor, this issue doesn't apply; using RealTerm I've come to the conclusion that it must be the DTS/RTS lines that have to be kept high for the ESP to perform deep sleep and reset correctly. It would be great if we could set the DTS/RTS lines in the monitor (there is already a Dtr toggle but its tooltip is confusing). Keep up the good work

	Thanks, I'll take a look to see if there are some new build config flags

	An rts checkbox has been added to the monitor for the next release. The tool tips have been improved. Arduino boards historically auto-reset with dtr enabled and do not use the rts. Q: What cable are you using and how are you connecting for the auto reset to work with the esp8266?

	It seems NodeMCU is using DTR/RTS for their ESP8266 module, you can have a look at the schematic here https://raw.githubusercontent.com/nodemcu/nodemcu-devkit/master/Documents/NODEMC.... Note that the components in the schematic differ a bit from models to models; I have one with a CP2102 on it.

	Rts was in the release a week or two ago. A problem with Dtr was fixed in yesterdays release
