Serial works on the ESP8266; SoftwareSerial fails to compile (I think it is available as an external library though). I was testing this for an ESP8266 project so it will work. I'd say it is a harware issue on the uC.

@frarugi87 Yes, I tried swapping – about ten times. Maybe my ESP8266 will work with Serial; I'll give it a try. Do you know if it supports SoftwareSerial?

@frarugi87 I don't think SoftwareSerial serial(0, 1); worked either.

| Nov 6, 2015 at 18:34 | comment | added | Dodo | @jwpat7 'Doesn't work' means no byte is received. The external device supports 38000 bps only, and the Arduino can use it on the hardware serial port (as tested connected to a computer with a Processing sketch). The fact that it is simultaneously connected to a computer through the USB port doesn't seem to be an issue, because it exhibits the same behaviour powered by a phone charger (unless the charger also interferes with something?). | |
| Nov 6, 2015 at 15:18 | comment | added | James Waldby - jwpat7 | 38000 bps is not a standard rate and hardware at one end or the other might not support it, while software might not care. You still haven't said what "doesn't work" means, but if it means garbled characters, use a standard rate, eg 38400 bps. | |

What if you try SoftwareSerial serial(0,1);?

| Nov 6, 2015 at 6:27 | comment | added | Dodo | @NickGammon This is interfacing with a CASIO fx-9750GII. I can receive the request byte from the calculator using SoftwareSerial but not with Serial. If the Arduino receives any data it makes a sound. | |
