Can't connect to USB serial port with nios2-terminal

I have a Bemicro board, which includes a FTDI virtual com port, and I cannot connect to it using nios2-terminal under windows. The com port is COM4 and hyper-terminal works perfectly.

When I use "/dev/com4", nios2-terminal responds that there is no such file or directory. I checked and there is no "\dev" directory. I'm not sure if cygwin will handle this on the fly or not.

Can anyone help me out?

    Sorry, didn't work. Same error: 

    
$ nios2-terminal --uart --port=/dev/tty4 --baud-rate=115200
nios2-terminal: can't open uart: No such file or directory
    I tried tty0 to tty5. I am trying to use COM4.

    No "dev" directory.
