Return cursor

I am sending data through the RS232 and read it using some terminal.
When I read it as a string and send WriteByte('\n');
WriteByte('\r');
the cursor is returned to the begining of the next row.
How can I do the similar thing when reading it as HEX in the terminal?

You are doing this the wrong way around. Traditional terminals send the end of line sequence <CR><LF> being carriage return and line feed respectively. Most applications expect a line to be terminated either with a <CR> or a <CR><LF> Lots of applications fail when the <LF> preceeds the <CR>

You should be doing

If you meant how do you get a terminal display that is showing the hex representation of characters to display a carriage return and line feed then the answer is you cannot because in hex mode it will desplay the hex value of these control characters[/quote]

Yes, thats what I meant.
Bad news.
Is there a terminal which allows me to do that?
I mean to see numbers in HEX but with returning the carriage after certain amount of sent bytes.
In other words to vombine the HEX view and string together

Termial by Br@y can display both ASCII and Hex (and binary and decimal) simultaniously.

At the right side of the Receive window there are three check boxes, "Dec", "Hex", and "Bin". Check what you want to see.
Warning: I suspect that if I check them all and the serial data comes in real fast, ie. high baud rate, long strings, small inter-character spacing, on my PC I may miss an occasional character. Therefore don't display all formats if you don't need them.
This is my favorite serial comms program!

The main Receive window shows the ASCII values of the bytes, and executes the <CR> and <LF> characters. Simultaniously the Hex window shows the hexadecimal values of the bytes, executing nothing.
What else are you looking for?

P.S. I just noticed the latest version has custom baud rates! So now if your clock is 5% slow you can use 9120 baud instead of 9600. I haven't seen that in a serial program since DOS days! I'll have to test it to see what the granularity is at high baud rates.

Hi Alex,

What you are asking for does not make sense because on one hand you would like to see the hexidecimal value of a character and on the other you want the application to respond to control characters. If the application was to correctly interpret <CR> and <LF> then you would expect it to also correctly interpret cursor commands up, down, left, right, erase to EOL, erase to BOL etc. You can't have it both ways :-)
