Page 3-27 CONFIGURATION
Custom Configuration (Group #70)
These options accommodate specific applications that may be installed at
the user’s site.
70 — DisplayWrite 370 support
DisplayWrite 370 is a word processing application that provides the
capability to bold, underline or overstrike text. DisplayWrite 370 printing
features are supported by the 6287 ALLY PLUS when this option is
enabled. To use these features, the user should read and understand Section
4 — Programmable Function Strings. To use all of the DisplayWrite 370
features, this option must be enabled, and the appropriate programmable
function strings must be programmed. They are listed here:
DESCRIPTION PFS
BOLD ON %02
BOLD OFF %03
OVERSTRIKE ON %04
OVERSTRIKE OFF %05
UNDERLINE ON %06
UNDERLINE OFF %07
To enable or disable this feature, use the following sequences:
!ALLY!70=00; DisplayWrite 370 is disabled (default)
!ALLY!70=01; DisplayWrite 370 is enabled
With DisplayWrite enabled, the data stream is handled in quite a different
way than when DisplayWrite is disabled:
When DisplayWrite is OFF, the data stream is sent to the printer one
character at a time as it is received. In this mode, it is permissible for the
user to embed printer-specific escape sequences or PFS commands
(!ALLY!>PFS#) in the data stream with predictable results. However, users
with laser printers will be unable to achieve bolding of text unless they
invoke a bold font.
