Hi,
TWR-VF65's SCI1 is connected with TWR-SER RS232C port.
However, SCI1_CTS/RTS are not connected with TWR-SER
CTS/RTS. Instead SCI0_CTS/RTS are connected.
Why is TWR-VF65GS10 implemented like that? How can the
user use the flow control on the RS232C of TWR-SER?
Best Regards,
Hiroki

Hi Hiroki,
The reason is that the UART1 CTS/RTS signals were being used for other functionality as well as muxed with UART2 which is being used as the secondary UART option, and the main priority for both was basic UART functionality.
However as a work-around for flow control, you can simply connect B35 to B21 and B39 to A9 on the primary elevator side, which connects UART1 RTCS/CTS to the RTS and CTS pins of the TWR-SER respectively.

Hi Anthony,
Thank you for your reply.
I understand it.
