|
* SLTT_TRANSP_ACS_PATCH (#define/#undef):
|
|
*
|
|
* The problem: some terminals (e.g. QNX/qansi*) map the whole upper half of
|
|
* the ASCII table to the lower half, when alt-char-set is activated with
|
|
* the smacs/as string-sequence. This means, that if 0 <= ch < 128 written
|
|
* to the terminal, it will be translated to (ch+128) automatically by the
|
|
* terminal: so not only the line-drawing characters can be written, when
|
|
* the alt-char-set is activated. It implicitly means, that space, NL, CR,
|
|
* etc. characters (exactly: anything besides the "standard" line drawing
|
|
* characters) can not be written directly to the terminal, when the
|
|
* alt-char-set is activated, because writing these characters doesn't cause
|
|
* an implicit/temporary switching-back to the standard char-set!
|
|
*
|
|
* The original code in SLang assumes that space, NL, CR, etc. can be
|
|
* printed when alt-char-set is activated. If SLTT_TRANSP_ACS_PATCH is
|
|
* defined, the modified code will not use this assumption.
|
|
* [Remark: the patch-code is not the most exact solution, but works...]

* (->SLTT_TRANSP_ACS_PATCH).
|
|
*
|
|
* If QNX_QANSI_SLANG_COMPAT_ACS is defined, the default smacs/sa, rmacs/ae,
|
|
* acsc/ac [and sgr/sa, if it would be used!] command sequences will be
|
|
* replaced internally with the "old style" (pre-QNX 4.23) sequences in case
|
|
* of QNX/qansi terminals. Using these optional command sequences the terminal
|
|
* remains compatible with the original SLang code (without using the
|
|
* workaround-code enabled by defining SLTT_TRANSP_ACS_PATCH).
