currently active during this process, they really should not be used until the entire message has
been displayed.
NOTE: Display on EOM does not support the use of MS110A 4800bps uncoded.
“FIFO” - When "Display on EOM" is not checked and "FIFO" is checked, the latest message
received shall be inserted at the top of the messages displayed buffer and done so character by
character during decoding. Other, when “FIFO” is not checked, each message will be appended
to the message buffer.
“Save on EOM” - When "Save on EOM" is checked, regardless of whether "Display on EOM" is
checked or not, all messages received shall be saved to the “../dalog/” sub directory using a file
naming convention of mmddyyyy.da in an ASCII text file that can only be read from start to end
when M110A is not running. The file contents can be read at any time as the file is opened,
written to and then closed. However if the file is opened for reading during incoming data, the
file must be closed and reopened to see all the data written to file since it was opened for
reading. See Appendix C for more details on the .da file.
“EOM Alarm” - When "Display on EOM" and “EOM Alarm” are both checked, the receipt of an
EOM will cause an audio alarm to sound on the systems default sound device. This feature
should not be enabled if the default sound device is actually being used as the PC sound device
modem.
“Common” - When checked the “Common” panel is always displayed.
“HEX Eng. View” – When “HEX Eng. View” is checked all data displayed in the Message Window
and logged will be the HEX byte value for each data byte received. This feature for the user is of
the most interest when monitoring binary data streams in SYNC or SYNC_EOM mode, which
cannot be displayed as pure ASCII characters correctly or for third party developers. A good
reference for the full ASCII character set is: http://www.ascii-code.com/
