Out of Curiosity. I wanted to ask If any one tried uploading sketches onto Arduino using MCP2200 based USB to UART ? Is it able to Reset the Arduino for programming ?
as long as you can see the com port(windows) in the arduino ide, you should be able to use it.
I have used usb to serial chips from everyone(ftdi, microchip, silabs, prolific) they all require dirvers, but once installed they all work the same as far a windows is concerned.
reseting the arduino requires one of the handshaking lines,iirc DTR needs to be connected to the reset through a 0.1uF cap.

MCP2200 does not have DTR hardware flow control ! Is it still possible to upload sketches using MCP2200 based USB to UART
without proper reset signal from usb, you would need to cycle the power or manually reset the arduino.
I seem to remember that once upon a time RTS was used as an alternative to the standard DTR-Reset in some older Arduinos and the IDE. Do I remember incorrectly and/or have they removed the RTS capability in the current IDE ?

this makes sense, the 2 major types for the ftdi boards used for arduino pro seem to have some with DTR and others with RTS.
this may be totally dependent on what arduino firmware/board version.
