Thanks,
But this was running before?

This is some changed Example MultiSerial:
/*

*/

void setup() {
// initialize both serial ports:
Serial.begin(9600);
Serial2.begin(2000000);
}

void loop() {
// read from port 1, send to port 0:
if ...

I was project with 2.6.0 and compiles well. Today Arduino IDE 2.2.1 was self updating with 2.7.0 and began give error with Serial2
