Macintosh Communications 291
For
this example,
we
will assume
that
the remote compu-
ter
is
calling the Mac. This situation
is
the reverse
of
our
previous two examples.
We
will also assume
that
the IBM
PC
XT
utilizes
an
emulator for which
we
have configured the Mac.
Set
up the Mac as before
and
select Wait
For
Call from the
Commands
menu.
The
modem will wait for
an
incoming call.
The
modem will answer the
phone
and send out the tones
required
to
establish the connection.
Once the Connect message has appeared on the
Mac
display, the IBM
PC
XT
is
on
line with the Mac. Any charac-
ters entered
on
the MacTerminal document will also
appear
on
the
IBM
PC
XT's display. Conversely, any characters entered
into the
PC
XT will
appear
on
the MacTerminal document.
Normally, this sort
of
communications link
is
only capable
of
data
transfer. The remote computer usually controls only the
displayed characters
of
the local computer. You probably will
not
be able
to
open
and
edit the remote computer's files
through such a link.
Let's transfer a file
to
the remote computer. There are two
methods which may be used
to
transfer
data
files.
The
first
is
to
write the file on the MacTerminal document; the second
is
to
use the Send File item in the File menu. To use the first method,
save
and
close the MacTerminal document. Open a document
which you wish
to
transfer, a
Mac
Write document for instance.
Use the
Copy
command
of
the Edit menu
to
put
the desired
text
on
the Clipboard. This allows you
to
transfer only a
part
of
a file instead
of
the entire file. Reopen the MacTerminal docu-
ment
and
select
Paste
from the Edit menu. The text should
appear
on
both the local and remote computers' screens.
The
second file transfer method involves using the Send
File item
of
the File menu. Select this item,
and
the available
documents will appear. Select the desired file, and the
Mac
will
accomplish the transfer. The file will not
appear
upon
the
MacTerminal document. Instead, the
Mac
will display a box,
such as the one depicted in figure 8.23, informing you
of
