Serial.ignoreFlowControl(true); //disable DTR

Many thanks for this awesome stack.

I understand the following issue has been previously discussed (~2020) but I cant see a solution anywhere.

Occasionally flowControl eg DTR is not set by the software for Serial data transmission and hence the MCU can not transmit the data hence integration cannot occur. Is there a way that FlowControl setting can be added as an option? (as implemented for RPico here https://github.com/earlephilhower/arduino-pico/blob/master/cores/rp2040/SerialUSB.cpp)

Ideally
Serial.ignoreFlowControl(true); can disable flowControl

Thanks a million

Start by comparing the linked RP2040 SerialUSB.cpp implementation and locating the Serial flow-control entry point in this library. The requested change is an option such as Serial.ignoreFlowControl(true) that disables DTR flow control; done means the MCU can transmit without that control signal being set.
