CHDouble

Received
CHSWITCH
characters appear
once
(not
doubled).
ON
Received
CHSWITCH
characters appear
twice
(doubled).
Set CHDOUBLE
ON when
operating with multiple
connections
to tell the difference between
CHSWITCH
characters received from
other stations
and CHSWITCH characters
generated
by
your
PK-
96. In
the fbllowing example
CHDOUBLE is
ONand CHSWITCH is
ser ro
"t"
($7C):
I this is a
test.
The
sending
station actually
transmitted:
I this is
a test.
The same
packet
received with
CHDOUBLE
OFFwould be displayed
as:
I this is
a test.

CHECK sets
a time-out value
for a
packet
connection if the distant station hasn't
been
heard
fiom lbr
CHECK
x l0 seconds.
Without the
CHECK feature,
if
your
PK-96 were
connected to
another station and the other station disap-
peared,
your
PK-96
would remain
connected indefinitely, perhaps
refusing
connections from other sta-
tions. Your
PK-96
tries to
prevent
this from
occurring-depending
on the settings of AX25L2V2
and
RE-
CONNECT-by
using the CHECK
timer as follows:
'
If
a
Version
I link is inactive
for
CHECK x 10 seconds,
your
PK-96 tries
to
save
the
link
by starling a
reconnect
sequence. The PK-96
enters the
"connect
in
progress"
state
and
sends
"connect
request"
frames.
'
If a Version
2 link
(A)€5L2V2
OM
is inactive
and
packets
haven't
been heard from the other station fbr
"n"
x l0
seconds,
your
PK-96
sends a
"check
packet"
to test if
the
link still
exists.
If your PK-96
doesn't
get
an
answer to the
"check
packet"
after RETRY+,/
attempts, it will
attempt to reconnect to the other
station.
See the RELINK
command.
