Thanks for clarification.
Yes, message appears, 256 colors works.
However, CR/LF looks weird. Checking my code now...

One more question.
set t_AB=^[[48;5;%dm
set t_AF=^[[38;5;%dm
does not works for me. I have to change "^[" to real \x1B (Esc) symbol. Is this
correct?
Yes, it is. To Vim, the following are equivalent and (I think) cannot be
told apart:
- Ctrl-@ and Nul (0x00). But since a null byte is not permissible inside
a line of edited text in Vim memory (in C, null bytes are string
terminators), nulls in the text are internally replaced by newline
characters (which would not be present because they signal a line
break), hence: also Ctrl-J and Nul (Ctrl-J is normally Linefeed, 0x0A).
- Ctrl-H and Backspace (Ox08)
- Ctrl-I and Tab (0x09)
- Ctrl-M and Enter (0x0D)
- Ctrl-[ and Esc (0x1B)
- Ctrl-? and Del (0x7F)
All this because they have in each case the same representation in the
ASCII code, which used to be a 7-bit papertape code long before personal
computers had even been imagined, unless maybe by science fiction
writers. The Ctrl key used to be a hardware trick to disable the higher
two of the 7 paper-punch bits, so that keyboards could afford to have
fewer keys. Similarly Shift would disable the 2nd bit from top, so that
a (0x61) became A (0x41) etc.
The ^[ in those two termcap entries is not a caret followed by a square
bracket, it is a control-bracket (a single byte) which is one of several
notations for the Esc character. I think you could use
backslash-specials with :let, as follows:
:let &t_AB = "\e[48;5;%dm"
:let &t_AF = "\e[38;5;%dm"
(see :help expr-quote) (DISCLAIMER: untested)
or, you could input the ^[ escape by Ctrl-V prefixing but that's tricky
business: you would perhaps need a different number of Ctrl-V characters
when typing the ex-command at the keyboard or when writing the line in
your vimrc, and I'm not sure how to make sure you got the right number.
It also would be much less legible than the \e notation in double quotes.
Best regards,
Tony.
