Epson LX-80 User Manual page 109

The printer's high- order control codes from 128 to 155 mirror
their low-order counterparts (O-27). In some cases it is necessary or
more convenient to use the high-order codes instead of the low-order
ones. For example, if your system will not send a 9 for a horizontal
tab, use 137 instead. For ready reference, both sets are listed here:
High
L o w H i g h
Dec Dec Hex
128 80

135 87

136
8 88
9 137 89
10 138

18 146 92
20 148 93
24 152 97

25 153
27 155 9B
Note: The high-order control codes cannot be used if the special
graphics characters are activated.
