Hi,
I am testing UART communication operation with the sample USB-UART bridge (cyfxusbuart) that comes with the EZ-USB FX3 SDK 1.3.4.
Using Tera Term on a Windows PC, I was able to send and receive ASCII code without any problems.
However, the BREAK signal cannot be transmitted.
Similarly, using Tera Term, the BREAK signal can be transmitted with the FTDI FT4232H.
Therefore, I think that the setting of TeraTerm is not a problem.
Could you please teach me how to send a BREAK signal over the FX3's USB-UART bridge?
Best Regards,
Taguchi

Hi Taguchi,
BREAK command comes with a bmRequestType 21h and bRequest 23h. Kindly handle the parsing of break character to the UART lines in the usbuart firmware in the FX3 SDK.
