So I have a device that holds itself in reset until the DTR line is
asserted. Once it is asserted, a message is sent from the device.
Using ftdi_sio I was able to just set the baud rate to 0 to deassert
DTR and set it to a proper baud rate to assert it. In libftdi it throws
an error when I try to set the baud rate to 0 which makes sense.
After looking I saw the ftdi_setdtr function so I thought I could use
this to achieve what I needed to do. Unfortunately this seems to do
nothing to DTR and yet returns no errors. Is there something that
needs to be done prior to using this function?
I may just be dumb and not seeing something obvious so be gentle. If I
need to do some more debugging I can do that, but some pointers on
where to start looking would be appreciated.
For reference the ftdi chip is a 232BM.
