How To Send Rs232 Commands
Rs232 Command Prompt
I bought the RS232 cable but i simply have NO IDEA AT ALL on how to send commands once i connect the pc to the screen using the RS232 cable (there is no nice-and-easy plug-and-play pop-up). Setup, which will be connected and used to control the CS261 via RS-232. Page 5), you can use the instructions below to send RS-232 commands to.
All devices on Unix are mapped to a device file, the serial ports would be /dev/ttyS0 /dev/ttyS1. First have a look at the permissions on that file, lets assume you are using /dev/ttyS1. Ls -l /dev/ttyS1 You will want read.write access, if this is a shared system then you should consider the security consequences of opening it up for everyone. Chmod o+rw /dev/ttyS1 A very simple crude method to write to the file, would use the simple echo command. Echo -ne ' 033[2J' > /dev/ttyS1 and to read cat -v. All you have to do is open two terminals.

In the first terminal you cat everything from the device, e.g. Cat /dev/ttyS0 in the other terminal, you can send arbitrary hex characters and text to the terminal e.g. As follows: echo -e ' x7E x03 xD0 xAF und normaler Text' > /dev/ttyS0 The echo -e command enables the interpretation of backslash escapes. One has to make sure of course that (i) the serial settings (speed, word length, flow ctrl, etc) are correct and (ii) the serial device (on the other end) is not blocking. Alternative to proxima nova.
