Is it possible to send data to the serial port through the ubuntu console?

Question

linux

I want to blink the LED of an arduino connected to a computer on Linux, with an Apache, from an iPhone. in php, you just need to enclose the command in back quotes. the only question is which command? Transmission speed 9600. The simpler the solution, the better.

Answer 1

No commands. Communication with the port is carried out both through the file :: arduino.shopium.ua/pages/arduino-and-php

Answer 2

Tell me, how can it be as simple as possible to send some test data to the com port through the terminal or a python script ??? In order to at least check the correct installation of the driver under Ubuntu under the RS232 Viewcon e066 adapter, did anyone do this at all?
