7–127Digital Emulation
Selecting IBM Proprinter Emulation via SOCS
Digital emulation is the default when printer power is turned on, but you can
select Proprinter emulation with one control sequence, the Select Other
Coding System (SOCS) sequence:
ASCII: ESC % =
Hex: 1BH 25H 3DH
SOCS resets IBM emulation mode to its initial conditions, which include:
• Downloaded buffer
• Character and line pitch
• Character attributes
• Print density
• Form length
• Tabs
• Active Character Set
The only valid Digital–compatible commands in IBM emulation mode are
ROCS, RIS, and DECSTR.
To exit IBM Proprinter emulation, enter the following escape sequence:
ASCII: ESC % @
Hex: 1BH 25H 40H
You can also exit from IBM Proprinter emulation mode by issuing a Reset to
Initial State (RIS) or a Soft Terminal Reset (DECSTR). Both of these
sequences perform the same reset function. Do not use the CSI control code
in the DECSTR control sequence; instead, use its 7–bit equivalent of ESC [.
