FLASHPCT.EXE
The Flash Management Services TSR API is for debugging use on the development PC only.
It is not designed for use on the PDT 3400 terminal. This TSR allows developing and testing
of applications which use the Flash Management API.
POWER34T.EXE
The Power Management Driver TSR API provides operating-system level power
management. Use this TSR instead of the POWER.EXE TSR supplied with MS-DOS. While
POWER.EXE can be used on the PDT 3400, it cannot be used in conjunction with
POWER34T.EXE, and does not provide as efficient a power management. POWER34T.EXE
requires that XBIOS34T.EXE or XBIOSPCT.EXE be loaded first and will not load unless one
of these two files is present. When used on the development PC with XBIOSPCT.EXE, this
TSR can be used for testing power management functionality of an application on the
development PC.
XBIOS34T.EXE, XBIOSPCT.EXE
These TSRs provide extended BIOS-level functionality specific to PDT 3400 features. Load
XBIOS34T.EXE on the PDT 3400 terminal ONLY as it uses PDT 3400-specific hardware.
XBIOSPCT.EXE can be loaded on the development PC for use in testing and debugging PDT
3400 applications on the development PC. Although the API for the two TSRs is the same,
XBIOSPCT.EXE does not act on certain commands because the required hardware is not
present. The return values, however, fall within those defined for XBIOS34T.EXE, allowing
useful testing and debug.
SCN1D21T.EXE
The DOS Scanner API provides one-dimensional bar code scanning support and supplies an
API for controlling scanning from an application. This TSR requires the presence of
POWER34T.EXE and XBIOS34T.EXE to load. Additionally, this driver requires the presence
of PDT 3400-specific hardware, and cannot be loaded on the development PC (even if
XBIOSPCT.EXE is loaded instead of XBIOS34T.EXE).
