I have a USB RFID reader and I need to get the DTR input high to get it to wake up. Seems like the VB/Python serial wrappers both have a parameter setDTR(boolean). Is this something that can be added to the Serial DAT? I can always use an external program but I just thought it would be fun to do RFID in Touch.
Hi James.
It’s currently not an option, but its something we can add as an option:
DTR control: enable / disable / handshake.

Cool. It will probably be needed by anyone else that wants to use the parallax usb rfid reader with Touch in the future so might not be a total waste of time.
cool. It sounds pretty straight forward from what I’ve read.

Alright it will be in the next build.
That is, control of both the DTR and RTS lines (disabled, enabled, handshake)
In addition the RTS line has a toggle option.
One thing to note, is that the DTR line seems to be enabled by default (at least in the internal comm port I was testing with). Perhaps its different default with different hardware and drivers.
Cheers,
Rob.
Hmm… that’s not very encouraging. Any idea when this will be released so I can test it out with my reader again?
