4.3 Sending and Receiving Messages
4.3.1 Entering and Deleting Messages
Entering Messages
There are two ways to enter messages:
1. If you want to send a message to your 545B's default destination (set with the
DESTINATION command), enter the MESSAGE command with no parameters by
following these steps:
a. Type MESSAGE. The computer enters the edit mode. If you decide to exit the edit
mode before transmitting a message, type [CTRL]A.
b. Enter a message up to 3,570 characters in length, pressing [CR] at the end of each 80
character line. To correct mistakes made upon entering the message, see Section
4.3.3.
c. After entering the message, press the [ESC] key. The [ESC] key queues the message
for transmission.
The computer prints the following message:
hh:mm:ss Message No: name:sss, nnnn chars, nnn segments
hh:mm:ss ROUTING name :sss TXT sss/nn TO: name
NOTE
If you want to use source routing, enter 0 for the destination ID. When the Master Station
receives your message, it will send the message to the appropriate destination, based on its link
table showing which destination(s) are linked with your Station (the source Station where the
message was sent from). Refer to the Master Station manual for more information on source
routing.
Messages entered in this fashion have a priority of R. If you want to send a message with a
higher (or lower) priority to your default destination Station, enter MESSAGE,p where "p" is any
letter A (top priority) to Z (lowest priority). If you also want to send the message to another
Station, refer to step 2 following.
2. If you want to send a message to another Station in addition to or instead of your default
destination, enter the MESSAGE command with priority and destination parameters by
following these steps:
a. Type: MESSAGE,p,dest1,dest2...
