Details:
There're lots of arduino clones using ch340g usb converter - which uses ch341
linux driver. However latest (newer than 6.0.1) avrdude doesn't get serial
settings from these devices (with error "Cannot get serial port settings").
The function ser_setspeed tries to get settings using ioctl(fd->ifd,
TIOCGSERIAL, &ss) - unfortnatelly the ch341 (nor the ch34x from the chipset
vendor) doesn't implement any ioctls.
avrdude 6.0.1 (and older) doesn't do all the ifdef magic for different OS, and
it works as expected.
