Hi, everyone. I'm pulling my hair out in great chunks. I need to get Python 2.5, using pyserial 2.2, to open a FTDI-based usb to serial port at 250000 baud. The FTDI chip definitely supports this rate. The port mounts at /dev/cuaU0. The problem is that /usr/local/lib/python2.5/site-packages/serial/serialposix.py fails on this line: ispeed = ospeed = getattr(TERMIOS,'B%s' % (self._baudrate)) So far, I have applied these patches to uftdi.c and uftdireg.h: http://tinyurl.com/2yye2l Approaching this with a machete, I have also updated /usr/src/lib/libc/gen/termios.h to add B250000, and rebuilt world and the kernel, and confirmed that the updated termios.h made it to /usr/include and /usr/include/sys. Any ideas on how to get this to work? It doesn't seem like it should be this difficult! Thanks -Brooks
