# Serial Ports seems to not work anymore

What's problem you are encountering?

I'm having problem with the "Serial ports" library
When i'm trying to start it, it seems to require additionnal parameters, all undocumented.

Fixes attempted
Addition of such parameters, with no success due to lack of documentation.

Welcome to the forum!

I don't know what you mean about additional parameters. Could you post a screenshot or something?

It works for me...
This simple Arduino sketch responds with the letter next to the received one.
Tested on ESP8266.

Echo.ino
void setup() {
Serial.begin( 115200);
while (!Serial) {}
}

void loop() {
if (Serial.available()) {
Serial.print( "Echo:");
