Serial1.write disconnect USB console

Thanks again.
In fact I Added a"SoftwareSerial" TX function so that I can control several devices with one espruino . And it works amazingly well !

  function softwareSerialTX(pin, arr) { // 9600, 8N1
    var baud = 1000/9600;
    let i, j, len;
    let binArr = [];

    len = arr.length;
    for (i = 0; i < len; i++) {
      binArr.push(0);

      for(j = 1; j < 256; j *= 2) {
        binArr.push((arr[i] & j) ? 1 : 0);
      }

      binArr.push(1);
    }
    binArr.push(0);

    let pulseArr = [];
    let start = binArr[0];
    let v = start;
    let cnt = 1;

    len = binArr.length;
    for (i = 1; i < len; i++) {
      if (binArr[i] == v) {
        cnt++;
      } else {
        v = binArr[i];
        pulseArr.push(cnt*baud);
        cnt = 1;
      }
    }
    if (cnt) {
      pulseArr.push(cnt*baud);
    }

//console.log(arr);
//console.log(binArr);
//console.log(pin);
//console.log(start);
//console.log(pulseArr);

    digitalPulse(pin, start, pulseArr);
  }
