PK-232 MBX Operating Manual - N3UJJ

Enter a short (up to 27 character) description of the subject of the
message. The MailDrop will then send the message prompt:
"Enter message, ^Z (CTRL-Z) or /EX to end"
After entering the message there are two ways to end the message.
Either the may be entered followed by a carriage return, or
the 3 characters "/EX" and a carriage-return on a line by itself will
end the message being sent. After this the MailDrop prompt should
appear indicating that the MailDrop is ready for another command.
After ending the message, if you or the calling party see the message
"*** No free memory", this means that the message was too large for
the available MailDrop memory and has been deleted. If this occurs,
you must shorten the message to fit into available memory shown in the
MailDrop prompt, and re-send the message.
When logged on from your local keyboard, if you use the "S" command
without a call sign, you'll see the error message "*** Need callsign".
However, a calling station may use the S command without a call sign;
it is understood that the message is directed to the PK-232's SYSOP.
As soon as a calling station uses the S command to send you (the
SYSOP) a message, the STA light starts blinking to show that a message
has been left for you. When you log on to your MailDrop with the
MDCHECK command the STA LED will stop blinking.

Private, Traffic or a Bulletin. A "P," "T" or "B" after the message
number shows the status of every message. A user sets this with the
SP, ST and SB forms of the Send command. The SYSOP may set this with
the Edit (E) command described above. If only S is used as the Send
command, the MailDrop will assign the message a Private (P) status.
The PK-232 MailDrop also accepts SEND commands of the form "SP SYSOP <
W1AW." The call sign after the "
