SPECIAL FIELD OBJECTS
Message Objects define special characteristics about the messages contained in
line 1 or line 2. These may define for example font size, sequence number, date
code, etc. There may be up to 15 Objects (special fields) for each line in a
message with the limitation that there can only be 1 sequence number imbedded
in a message.
'P' 0x50 Message Objects
(EV I, EV II, EV SC)
Q.
ESC|STX|Address|`P`|SOH|aabb|EOT
R.
ESC|STX|Address|`P`|'aa bb cc dd ee ff gggg hhhh'|EOT
Where: each set of 2 ASCII characters represent the upper and

aa = objects for which line 0 or 1
bb = number of objects transmitted. (Max 15)
Each object as defined by bb: (repeat the for each object)
cc

The above constitutes 10 object fields. Even though there are 48
characters permitted per line data entry will be inhibited when
the 15

alpha/numeric object, may contain enough characters to meet
the 48-character limit.
