Sending “ENTER” key through serial port

Question

Hi I want to send some command to my device which is connected via serial port. How to send it?

For example i found this on google search but for me it\'s useless.

To send the enter key, you would have to use

serial.Write(new byte[]{13,10}, 0, 2);

Assuming your syntax for Control + E is correct. The enter key is interpreted and usually saved in a file as CR-LF. However, depending on your device, it may only require CR=13, or LF=10. You should try all 3 combinations with your device to see what it expects.

If you are looking for the actual scan code of the enter key, it's "43" on a PC 102/104 key keyboard. Depending on the actually computer you are using, it may be different. For instance on a Commodore 64 the scan code for the Return key is "1", which has the equivalent use of Enter on a PC keyboard.
