PK-88 OPERATING MANUAL
PACKET OPERATION
4 - 19
PK-88 - 66
4.11.1
Default Multiple-Connect Conditions
At start-up time and until you change it, the PK-88 defaults to the following multiple-con-
nect conditions:
CHCALL OFF
CHDOUBLE OFF
CHSWITCH $00
USERS 1
These defaults set the PK-88 to operate exactly as would a TNC without the multiple-con-
nect feature.
4.11.2
The USERS Command – Multiple-Connect Active
The USERS command affects only the manner in which incoming connect requests are
handled, and has no effect on the number of connections you initiate with the PK-88.
A numerical value
n
from 0 to 10 specifies the number of simultaneous connections that
the PK-88 will receive. For example:
USERS 0
allows incoming connections on any free logical channel
USERS 1
allows incoming connections on logical channel 0 only
USERS 2
allows incoming connections on logical channels 0 and 1
USERS 3
allows incoming connections on logical channels 0, 1 and 2
and so on, through USERS 10.
4.11.3
CHSWITCH Character Selection
CHSWITCH selects the character used to change channels in multiple connect operation.
The value
n
0 to $FF (0 to 255 decimal) specifies the desired character.
o
CHSWITCH characters must not be channel numbers (0 to 9).
The PK-88's default for CHSWITCH is $00, which disables the function.
Set the CHSWITCH character to a hexadecimal value from $00 to $FF, for any character
that you will not normally use. You can switch 'logical channels' in a multiple-connect sit-
uation by typing the CHSWITCH character even when in the Converse Mode.
The CHSWITCH character can be PASSed in CONVERS mode, and is always ignored
TRANSPARENT mode; it just flows through as data. The outgoing channel in fact cannot
be changed while in TRANSPARENT mode.
4.11.4
The CHCALL Command – Display Multiple-Connect Call Signs
CHCALL displays the call sign of the 'connected-to' station after the channel identifier. Set
CHCALL ON
if you plan to use multiple connections.
4.11.5
The CHDOUBLE Command – Display Doubled Characters
When
CHDOUBLE
is set
ON
, your monitor displays received CHSWITCH characters as
doubled characters.
Setting
CHDOUBLE ON
helps you tell the difference between CHSWITCH characters you
type, and those received from other stations.
