4.6.2 The Channel Switching Character
The logical channels are selected with the CHSWITCH character. You
must choose a CHSWITCH character that you do not normally type such as
the vertical bar "|" (ASCII $7C), or the tilde "~" (ASCII $7E). Once
this has been selected and entered into the PK-232, you may initiate
multiple connections with others on your radio channel.
You can now initiate connects on any of the logical channels numbered
zero through nine (0-9). To change logical channels, press the
CHSWITCH character you just defined, and then a number from 0-9.
Remember that the test that you type will only be sent out to the
station connected to the logical channel your PK-232 is currently on.
4.6.3 Will You Accept Multiple Connects
Setting the CHSWITCH character only allows you to make outgoing
multiple connects. To set your PK-232 to allow incoming multiple
connections, you must set the USERS parameter to more than one (1).
The number you enter in the USERS command tells the PK-232 how many
other users you will allow to connect to you at on time.
4.6.4 Display Multiple Connected Callsigns
Multiple Connection operation can be confusing - especially
remembering who is connected on what channel. To help this, you may
want to turn ON the CHCALL command to display the callsign of the
station who is connected to you on a given channel number.
4.6.5 Doubling Received CHSWITCH Characters
If you want to be able to tell the difference between the CHSWITCH
characters you type, and characters from other stations that happen to
be the same as your CHSWITCH character, then set CHDOUBLE ON.
4.6.6 Checking Your Connect Status with the CSTATUS Command
To check what channels your PK-232 is currently set to, as well as who
is connected to you, you may find the CSTATUS command helpful.
CSTATUS is an immediate command that shows you the status of all 10
packet channels as well as the channel you are currently on.
4.6.7 The MULT LED
You will know you are connected to more than one packet station when
the MULT LED on the front panel of the PK-232 lights.
NOTE: The MULT LED will blink if the PK-232's receive buffer is
filled. This can happen if your computer is not connected
to the PK-232, or if for some reason, your communications
program no longer can accept any further inbound data.
