on windows: (win11)
set_options fails with ec 31 = 'A device attached to the system is not functioning'
if the option matches the desired value. workaround: get_options and only set_option if !=
but after closing the port I found that some Device Control Block dcp fail to be set that are not exposed by boost.asio
in my case:
BaudRate, fDtrControl, and fRtsControl
my current strategy is to use the winAPI and reset the dcp before port.close()
Am I missing a trick here? Or is this common, normal serial COM port hell?
