How do I add colour to a QNX terminal?

Question

I'm connecting to QNX Neutrino over SSH with PuTTY 0.62.

I've enabled "Allow terminal to specify ASCI colours", and "Allow terminal to use xterm 256-colour mode".

How do I get my terminal (qansi-m) to add colour to the output text?

Answer 1

You can manually add colours by using the following when using echo:

The graphic rendition codes are as follows:

Number  Meaning
0       All attributes off (except charset (10, 11, 12))
1       Bold
2       Half intensity (default to cyan on color screen)
4       Underline (default to red on color screen)
5       Blink
7       Reverse
9       Invisible
10      Exit alternate char set (GR & GL are restored)
11      Enter PC-lower char set (GR & GL are ASCII; C0 & C1 are PC_LO except for ESC)
12      Enter PC-higher char set (GR, C1 & GL, C0 are PC_HI except for ESC)
21      Normal intensity (un-Bold)
22      Normal intensity (un-Half intensity)
24      Disable underline
25      Disable blink
27      Disable reverse
29      Visible
30-37   Set foreground color (30+color_number, see below)
39      Set foreground to saved
40-47   Set background color (40+color_number, see below)
49      Set background to saved

The color codes are as follows:

colour_num  Description
0           Black
1           Red
2           Green
3           Brown
4           Blue
5           Violet
6           Cyan
7           White

Syntax:

{CSI}<setting1>;<setting2>m

CSI in octal is \0233, so to print bold text (1) with a red foreground (31), you'd do:

echo "\023331;1m"

You need to configure the programs you run on the Neutrino (including the shell) to send the necessary ANSI escape sequences. sshd can't intercept and modify the terminal output.
