Audible Tones - Dataman S4 Manual

DATAMAN S4 MANUAL
divided into pages of 16K bytes. S4 handles page
mode EPROMS as if
they had straightforward contiguous memory.
Swapping pages is handled
"behind the scenes" without troubling the user.
Thus there is no apparent difference in the way S4
handles a 27512,
which is one single block of 64k bytes, and a
27513, which is 4 pages
of 16k bytes.
The user must be aware of the real difference,
however, and how it
affects his system. Use of these devices is
described in manufacturers'
literature.
FUNC Key
The FUNC key is used like a shift key to access an
extra set of functions.
When waiting for a function the prompt becomes
* instead of >>
<$IBeeper>Audible Tones
S4 makes a variety of beeping noises:
A single tone is made on acceptance of a key.
A double tone low-high is a rebuke that a key is
not acceptable.
During the execution of those commands which
take several seconds,
"pips" are emitted every half-second to tell you
that the program
is working - except in the BURN routine, which
writes addresses
to the display.
An incoming data-file makes a recognisable
sound.
