/* Notes on ascii input:
Input is complicated because different systems have varying input models,
especially with regard to handling ^C. The CMT model handles ^C and ^G as
special characters, and these do not cause software interrupts. Also, the
lowest level of the CMT model does not support line editing: Every character
is acted upon immediately. This has two implications:
(1) CMT must "read ahead" looking for ^C and ^G characters. This is handled
by the check_aborted() procedure, which reads characters into the
type_ahead[] array.
(2) CMT must do its own line editing. This is handled by the ggets() routine.
A number of functions support ascii input, only some of which are visible
to the application programmer. Let's start at the top-level and work down;
each of the following calls the routine below it:
ggets() - gets a string with line editing support. This function is fairly
machine independent, except for some backspace-and-erase control character
code sequences.
ggetchar() - gets a raw character. This function calls wait_ascii()
and echoes it. Note that it may return ABORT_CHAR or BREAK_CHAR.
wait_ascii() - gets a raw character without echo and without character
code translation. wait_ascii() either polls get_ascii() or uses some
kind of system-dependent event waiting. Returns ABORT_CHAR or BREAK_CHAR
immediately if abort_flag has been set, regardless of whether there is
new ascii input.
get_ascii() - checks to see if a character is available. (Using
check_aborted().)
The only dependency here is on the Amiga, we restart input when buffer goes
from full to non-full.
check_aborted() - looks for input by calling ascii_input. If found,
put the input into the type_ahead[] buffer. Returns abort_flag.
ascii_input() - lowest level of input; just gets a character if there is
one. Does conversion from RETURN (\r) to EOL (\n). The Amiga handles
this in-line directly in check_aborted().
Here's a quick summary:
ggets = ggetchar + line editing & string building
ggetchar = wait_ascii + character echo
wait_ascii = get_ascii + wait for character
get_ascii = check_aborted + pull char from buffer
check_aborted = ascii_input + test for ^C,^G + put in buffer
ascii_input = poll for char + CR->EOL conversion

*
* io_init is not amiga specific : the simplest version

*
* for the Mac, it seems that ascii_input doesn't work unless getchar() is
