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

[Altera_Forum]

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?
