It seems to me that CTSRTS flow control is not implemented
in the device I have. I tried to send lots of data to cause level change
of the RTS signal with no success. Also I tried to:
1. open port;
2. disable CTSRTS flow control;
3. set RTS to a specific level;
4. enable CTSRTS flow control;
5. send some data.

I tried the sequence above with RTS set and reset, and I can conclude that
step 4 doesn't affect RTS signal at all.

Best regards,
Maksim.
