serial.pipe

Good suggestion, thanks Gordon, I tried that and got this:

Serial1.setup(100000, {rx:B7,parity:E,stopbits:2});
Serial1.on('framing', function() {
  console.log("frame");
  print(E.toUint8Array(Serial1.read(25)));
});

new Uint8Array([15, 174, 112, 133])
frame
new Uint8Array([43])
frame
new Uint8Array([92])
frame
new Uint8Array([225])
frame
new Uint8Array([10, 87])
frame
new Uint8Array([184, 194, 21, 174, 112, 133])
frame
new Uint8Array([43])
frame
new Uint8Array([92])
frame
new Uint8Array([225])
frame
new Uint8Array([10, 87])
frame
new Uint8Array(0)
frame
new Uint8Array(0)
