Transparent Mode
Converse Mode will often work well for computer data transfer,
but files such as a EXE file on a MS/DOS system, a BASIC
program, or even a word-processor text file, may contain char-
acters which conflict with special characters in Converse Mode.
If you transfer such files you will have to use Transparent Mode.
Transparent Mode recognizes no special characters — every-
thing you type (or everything your computer sends to the packet
controller) 1s sent over the radio exactly as it was received by the
packet controller. There are no input editing features and there
is no send-packet character. Packets are sent at regular time
intervals or when a full packet of information is ready. The time
interval
at
which
data
is
packetized
is
set
by
PACTime
.
The display characteristics of the packet controller are also
modified in Transparent Mode. Data is sent to the computer
exactly as it is received over the radio, including all 8 bits of each
byte
received.
Features
such
as
auto-linefeed
insertion
and
screen wrap are disabled, and echoing of input characters is
disabled.
The
parameters
that
control
these
features
in
Com-
mand Mode and Converse Mode are not changed by entering
Transparent
Mode,
and
all
display
features
are
re-enabled
when
the packet controller is returned to Command Mode. Most of
the link status messages that appear as the packet controller
moves between disconnected and connected states are also
disabled in Transparent Mode.
In order to permit the Command Mode entry character to be
transmitted freely in in transparent mode, you utilize the Com-
mand
mode
entry
character
in
the
following
way:
You
must
wait
for
a
time
period
after
typing
the
last
character
to
be
sent.
This
time is set by the command CMdtime. Following this wait, you
must
type
three
Command
Mode
entry
characters
(default
<CTRL-C> ) within an interval CMdtime of each other. After
a final CMdtime interval in which no characters are typed, you
will see the “cmd:” prompt.
