Error opening serial port: SYS_IOCTL: inappropriate ioctl for device

[bseishen]

Trying to get this working in Windows Subsystem for Linux. "SYS_IOCTL: inappropriate ioctl for device" when trying to open the port.

You need compile this little cpp app. And check output. Then change constants in code:

go-serial/serial/open_linux.go

Lines 14 to 25 in 15cf729

	// Grab the constants with the following little program, to avoid using cgo:
	//
	// #include <stdio.h>
	// #include <stdlib.h>
	// #include <linux/termios.h>
	//
	// int main(int argc, const char **argv) {
	// printf("TCSETS2 = 0x%08X\n", TCSETS2);
	// printf("BOTHER = 0x%08X\n", BOTHER);
	// printf("NCCS = %d\n", NCCS);
	// return 0;
	// }

Same problem on mips #27

But @philipgreat fix was very helpful.
