FTDI

Now I've skipped the linux-style-tty-code because it didn't support high baud rates. Instead I am using ftdi code.

#include <ftdi.h>
void setupUART(void) {
    int ret; 
    ftdi_init(&ftdic);
    if((ret = ftdi_usb_open(&ftdic, 0x0403, 0x6001)) < 0) { 
        fprintf(stderr, "unable to open ftdi device: %d (%s)\n", ret, ftdi_get_error_string(&ftdic));
    }   
    
    ftdi_set_baudrate(&ftdic, 115200);
    
    unsigned char buf[2];
    
    buf[0] = 0x55;
    buf[1] = 0xAA;
    ftdi_write_data(&ftdic, buf, 2); 
}

This is more simple than the previous code I used. And the baud rate is 115.2 kbaud. I will try to set it to even faster speeds and do some adjustments on the timing in the emulator code.
