Are you sure you want/need ischronous mode?

Isochronous (e.g. in USB or 1934/Firewire) type pipes are typically only
used for constant bit rate audio or video streams.

Chirp deals in serial ports.

Perhaps you want to turn off serial port handshaking?

It is off, by default unless the class sets HARDWARE_FLOW class variable.

If you want to double check the flow control settings, you can look at:

radio.pipe.rtscts
radio.pipe.dsrdtr
radio.pipe.xonxoff

-ch
