ioninja-hwc serialTap - inverted circuit

Hello again 🙂

One of the devices that we want to monitor has a TTL serial port, but with a strange customization. Its RX circuit is "regular", but the TX circuit is "inverted"... I do not know why... perhaps there is a real reason, perhaps they try to avoid use standard components...

Anyway, I am interested in capturing this communication using the SerialTap. I know (I did it before in lab) I could simply use an transistor in order to invert it, but this solucion is inconvenient when used in field (with real devices in operation), as we want that the setup that stands installed be clean and simple (and, eg, using the transitor solution, I have somehow to find a "5V Vcc")

I do not know it it would be possible to add an option in order to do this at "serialTap" level (eg. add an option to be able to consider some signals inverted, and apply some kind of "xor 1" over this circuits).

Regards!
