POSIX method for setting arbitrary (nonstandard) baud rate?
I have a USB serial adapter that supports arbitrary baud rates. To set a nonstandard rate in code, I'd been using the TIOCGSERIAL like so:

Code:
struct serial_struct ser_info; 
ioctl(ser_dev, TIOCGSERIAL, &ser_info); 
ser_info.flags = ASYNC_SPD_CUST | ASYNC_LOW_LATENCY; 
ser_info.custom_divisor = ser_info.baud_base / CUST_BAUD_RATE; 
ioctl(ser_dev, TIOCSSERIAL, &ser_info);

I'd like to make this portable, but the termios serial I/O API doesn't seem to support setting nonstandard baud rates. Is there a POSIX alternative to the ioctl() for doing this

That's precisely the sort of thing ioctl is for. You said it yourself -- nonstandard baud rates; there's not going to be much of a standard way to do it.
