How to do non-blocking writes using USBSerial
Hi:
In the Serial library, there is a function called readable and one called writable. However, in the USBSerial library, there is only a function named available, which is similar to the readable function. How can I check if the interface is writable? I need to do non-blocking writes to the serial interface. Is the function _putc blocking or non-blocking?
Thanks! T.H.
