I use RealTerm (http://realterm.sourceforge.net/) to connect the virtual com, and find out the CTS signal is set, and the result is nothing can be written to virtual com port.
How can I reset the CTS signal in virtual com?
Normally the serial handshake is:
1- you set your rta active
2- nak from other side is to set cts active
have you set your 'rts' active first?
