hi,
A very small doubt

I have two com ports on my pc ,if i connect a rs232 to my com port how can i recognize which terminal driver is activating that com port
eg:/dev/tty1 for com port1
I want to use minicom for debugging my embedded board using print statements

/dev/ttyS0 is the device ID for the first serial port.
/dev/ttyS1 is the device ID for the second serial port.

You will need to configure minicom to use the device that is attached to the embedded controller.

hi,

The data what my embedded board sends is in hex format F1,F2 likewise ....does minicom supports for ascii printing or hex format.

if ascii how to get the display in hex format

AFAIK if you do not know you just have to check. Swapping a line on a working port just takes a moment.

Perhaps it would be useful to know:
"To send text to a terminal you may redirect standard output of some command-line command to the appropriate special file. For example typing "echo test > /dev/ttyS1" at the command prompt should send the word "test" to the terminal on ttyS1 (COM2) provided you have write permission on /dev/ttyS1. Similarly, typing "cat my_file > /dev/ttyS0" will send the contents of the file my_file to COM1 (ttyS0)."

Also "screen /dev/ttyS0 115200" works.

minicom is ASCII data. You might have to write a program to convert the hex to ASCII. It might be possible to use the conversion table to produce readable text but I have not tried it.

Hi!

I have run into similar problem recently. I wanna send out a string "7e 01 09 00 ff ff 53 42 bc b7 7e" to a controller and when I write it on the minicom, I am never sure if it is being sent out as ASCII or Hex. I want it to sent out as Hex. How should I do that?

Thanks!

uibrahim,
cutecom is a GUI application that is capable of sending/receiving hex data.

Same thing you've been asking in your other thread that has received LOTS of replies...no real need to re-open a thread that's five years old and unrelated to your question.
