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. -- libftdi - see http://www.intra2net.com/en/developer/libftdi for details. To unsubscribe send a mail to [email protected]
