Hello,

I'm trying to communicate with the serial port using the example code "minicom" that was posted here: http://lists.boost.org/boost-users/att-41140/minicom.cpp
On Linux, the example works flawlessly and lets me communicate with both "native" serial port hardware and USB-to-serial converted hardware with FTDI chips, which can be adressed via /dev/ttyUSB.

On a Power Mac with OS Tiger, using boost 1.40 and the gcc 4.0 compiler, everytime I start the example I get the following errors:

$ ./minicom.app/Contents/MacOS/minicom 57600 /dev/cu.usbserial-4B11
Error: Operation not supported
Press Enter to exit
Error: Bad file descriptor
Press Enter to exit

However, I can talk to the serial-via-usb hardware using some native socket functions, so the file descriptor itself can't be the problem. 

How can I get the minicom example to work on Mac also?

Regards,
Philipp
