Serial Character Coding
TXT M
ODE
Character coding is in a serial format, with only one attributes being changed at any single location. The serial
attributes take effect either at the position of the attribute (Set At), or at the following location (Set After). The
attribute remains effective until either modified by new serial attributes or until the end of the row.
