FT232R and PICs connection

[dolyshor]

Hello,

I have the following situation:

hardware:     FT232R        PIC16F1938
                     TXD    tied with    RX
                     RXD    tied with    TX
                     RTS    tied with    MCLR
                     CTS    see below
software: Win7 32, ds30Loader GUI 1.5.7, driver for FT232R v2.10.00 (I know that there 
is a newer version but for this chip - FT232R - it's no difference); other software or 
firmware are not relevant for this discussion.
I have tried to write some firmware into the PIC either connecting CTS pin of the FT232R 
to ground or leaving it unconnected. In both situations I have been able to write 
correctly my firmware into the PIC regardless the settings in the GUI:
a) Reset tab: manual or RTS checked;
b) Basic tab\Flow control: None or Xon/Xoff or Hardware or Both.
So, the recommended schematic - I mean the connection of CTS to ground - from page 21 of 
the main manual, October 2012 version, and the above mentioned settings are required 
only when we are using a true, not a virtual, COM port together with the MAX232 shifting 
levels chip?
In that case, there is no longer needed a 5-pin connector, but a 4-pin one, to upload 
the firmware into the PIC.
Am I right?
