The main outgoing message buffer size is limited to 32k (32,378) at this time. If a message is
entered that exceeds the limit an error message will be displayed. If a message is entered that is
longer than will display in the window at one time, vertical scroll bars will automatically turn on
for scrolling and will turn off when the "Clear" button is used. There is no LINE WRAP taking
place, thus long lines will not wrap on the RX end.
NOTE: If any message content requires data encryption, the use of an authorized off line encryption
methods that produce ASCII output must be used where the resulting data is pasted into the “Outgoing
Message Window” for transmission. In addition, should the sending of any files be required, the use of
an authorized Binary to ASCII file conversion tools must be used where the resulting output is pasted
into “Outgoing Message Window” for transmission. It is recommended that any data which requires off
line processing to recover its meaning be sent three times as the FEC although robust, is not error free,
thus the user will need to verify proper data receipt by comparison prior to additional processing of the
off line data content. The use of the Data Port with external 3
rd
party terminals for error free
transmission negates the need to duplicate the data content.
Check Boxes
“Save on Send” - When "Save on Send" is checked, all messages sent shall be saved to the
“../owlog/” sub directory in the format mmddyyyy.ow as an ASCII text file that can only be read

for the current Zulu Date shall be displayed. See Appendix D for more details on the .ow file.
“Clear on Send” - When "Clear on Send" is checked the outgoing message window will be
cleared after the message has been sent.
“Insert TODz” - Per ACP-126 requirement "302. TIME OF TRANSMISSION INDICATOR - All
