HI All,
Using flow control on a Teensy 3.2 worked well for me.
I have decided to move up to the T4.1, but am having a few problems with hardware flow control.
For some context, I have Serial1 connected to an Xbee radio. Xbee flow control pins are connected to pins 2 and 3 of the T4.1 with pin 3 of T4.1 connected to the RTS pin on the Xbee. So pin 3 should be my CTS pin. This exact setup worked fine on the T3.2.
From the Teensy serial page -
Can anyone tell me if there is a way to use pin 3 as a standard CTS pin?
Maybe I require an inverting circuit?
Paul.

From the Teensy serial page -
* CTS polarity is inverted when connected through XBAR. Normally CTS is active low, meaning Teensy is allowed to transmit data when CTS is low, and must pause when CTS is driven high. But when using XBAR, Teensy transmits when the pin is logic high and pauses transmission while the pin is low.
