+            arrival_dn_arrow     :1,    bit 1
+            arrival_up_arrow     :1,    bit0
+
+3rd Byte:  Scan_slot. zero is reserved, 1 through 254, (119 may be max value in some cases)
+
+4th Byte: Message_number.  zero is no message, 1 through 126, (63 may be max value in some cases)
+
+5th Byte:  Is a bit field:    Rear arrival dn arr    :1,    bit 7
+            Rear arrival up arr    :1,    bit 6
+            Message level hi bit    :1,    bit 5
+            Message level low bit    :1,    bit 4
+            Passing chime         :1,    bit 3

+            traveling dn arrow    :1,    bit 1
+            traveling up arrow    :1,    bit 0
+
+6th Byte:  ASCII floor char, msb.
+
+7th Btye:  ASCII floor char, mid.
+
+8thByte:  ASCII floor char, lsb.
+            Note:  floor ASCII range is 0x30 through 0x5a (‘0’ – ‘Z’). 
+                0x3a  through 0x40 are special characters with 
+                0x3b being the space or blank character(semicolon)
+                0x3d is normally displayed as a minus character.
+9th Byte:  ASCII Mess. char, msb.
+
+10th Byte:  ASCII Mess. Char, mid.
+
+11th Byte:  ASCII Mess. char, lsb.
+            Note:  message ASCII range is 0x30 through 0x5b (‘0’ – ‘[’). 
+                0x3a  through 0x40 are special characters with 
+                0x3b being the space or blank character(semicolon)
+                0x5d is sent when there is no message (instead of spaces).
+                So bytes 9, 10, and 11 will each be ‘[‘  when no message. 
+12th Byte: checksum, two’s complement of bytes 1 through 11.
+
+Example:
+ 0x40,    header
+ 0x01,    up arrow for lantern
+ 0x01,     floor number 1,
+ 0x03,    message number 3 activated 
+ 0x11,    message level 1, direction arrow is up
+ 0x4c,    ascii floor character ‘L’
+ 0x42,    ascii floor character ‘B,
+ 0x59,    ascii floor character ‘Y’
+ 0x3b,    ascii message character ‘;’ for space or blank
+ 0x4e,    ascii message character ‘N’
+ 0x44,    ascii message character ‘D’
+ 0xf6,    checksum (two’s complement).
