4.4.7 Packet Formatting and Editing
Some of your PK-900's command parameters affect how your packets are
formatted - how your typing appears to the rest of the world. Other
commands let you correct typing errors before your packet is sent,
cancel lines or cancel packets if necessary.
4.4.7.1 Carriage Returns and Linefeeds in Packets
Most people use packet radio for sending and receiving messages or
conversing with other Amateurs. The character used to send a packet
is defined with the command SENDPAC which defaults to a Carriage
Return ($0D). The SENDPAC character may be changed, but most will
find the Carriage Return or Enter key to be a natural choice.
Similarly, your PK-900 will include a Carriage Return in the packet
you send to other stations since this makes for a more natural
conversation. The ACRPACK command (default ON) controls this feature,
but most people never want to change this.
The PK-900 also has the capability of adding a linefeed character
($0A) automatically to packets that you send to others. If you
encounter a station that says your packets are overprinting, you may
want to turn the ALFPACK or the ILFPACK command ON temporarily.
4.4.7.2 Canceling Lines and Packets
Most of the time, the Backspace key (or the Delete key on some
computers) is all that is needed to edit a line before it is sent.
Occasionally it may be helpful to cancel the line, or the entire
packet you are entering with one key stroke. The CANLINE character
(default <CTRL-X>) will cancel the entire line you are typing. The
CANPAC character (default <CTRL-Y>) will delete the entire packet you
are entering. These commands can be helpful, but use them with care.
4.4.7.3 Redisplay
If you have erased and retyped many characters, you may want to see
the sentence you are currently entering "redisplayed" by the PK-900,
especially if BKONDEL is OFF. Your PK-900 will show the line you're
entering when you type the REDISPLAY character (default <CTRL-R>).
This will also allow you to display any packets you might have
received while you were typing.
4.4.7.4 The PASS Character
If you are using a terminal or terminal program, the following may be
useful. Sometimes you may want to include a special input character
such as a Carriage Return (the SENDPAC character) in a packet. For
example, to send several lines in the same packet, you must include
<CR> at the end of each line. You can include any character in a
packet (including all special characters) by prefixing that character
with the PASS character (default <CTRL-V>):
I wasn't at the meeting.<CTRL-V><CR>
What happened?
Without the PASS character, this message would go out as two packets.
