RS232_INVERTED confusion

[marrold]

Hi,

I am trying to get my head around the RS232_INVERTED flag which appears to be the default for the ESP8266.

It defines the following:

define DEFAULT_RTS_ACTIVE HIGH

define DEFAULT_RTS_INACTIVE LOW

As I understand it, in the RS232 specification RTS is active high. But if we're using a MAX232 or similar it's inverted so we'd need the ESP to use active low.

Have I misunderstood something? I assumed the default ZiModem configuration would assume a MAX232 is in use.

Thanks
