Comment (by bittorf@…):
i think OP means BUSYBOX_DEFAULT_FEATURE_EDITING_MAX_LEN which defaults to
512 bytes.
when reading busybox/libbb/lineedit.c it seems this affects interactive
sessions only:
{{{
/* Make a local copy of the string up to the position of the cursor.
* build_match_prefix will expand it into int16_t's, need to
allocate
* twice as much as the string_len+1.
* (we then also (ab)use this extra space later - see (**))
*/
}}}
the questions is, if scripts called via odhcpc (or similar) can eat input
>512 bytes...
