Memory:
This

of
the

all
four

available
on
the
Altos

The
TPA

(User

has
been
increased
to

Bank

contains
the
CP

jump

and

A

The

The
printer

can
be
connected
to

with
two

(
The

Such

If

brought
up
on
both

It
does
not

If

Rates
There
are
several
versions
of
FTP
on
the
distribution

The
only
difference
between
the
various
v

is
the
baud
rate
used
for
the

The

is
the

that
uses

The

Experimentation
with
9609
vs
.
31250
baud
rates
shows
that
there
is
very
little
difference
in
total
transfer
time.
The
experiment
has
run
on
floppy
disk
systems;
on
hard
disk
systems,
there
might
be a
greater
difference.
Experimentation
shows
that
the
maximum
baud
rate
for
FTP
under
MP
/M
II
with
one
user
is
9699.
That
is,
only
FTP12, FTP24,
FTP48,
and
FTP
(
Le.
9600
baud)
work
on
MP
/ M
II.
If
more
than
one
user
is
active,
the
maximum
baud
rate
could
be
as
low
as
1200.
ProcedUre
The
sending
side
of
the
transfer
is
started
by
the
command:
PTP
<afn)
where
<
afn
>
is
an
ambiguous
file
name
as
described
in
the
CP
/ M
manuals.
For
example,
the
command:
F'l'P
*.0011
sends
all
of
the
.COM
fil
es
to
the
receiving
side.
Whereas:
FTP
FILE.
RAIl
sends
only
file
FILE.NAM.
's'
while
waiting
for
the
The
sending
FTP
periodically
types
an
receiver
to
become
active.
The
receiving
side
is
started
by
one
of
the
following
commands:
~
or
nP
a:
where
'u'
is
the
drive
letter
of
the
destination
disk.
If
no
drive
letter
is
specified,
the
logged
disk
is
the
destination
disk.
The
receiving
FTP
periodically
types
a
'WI
while
waiting
for
the
sender
to
become
active.
Since
the
recei
ving
side
normally
does
not
exist
by
itself,
enter
[CONTROL} C
to
get
back
to
CP
/M.
