Workstation Mode Application

M90 Series Portable Data Entry Unit Reference Manual
Although applications are classified into resident and transient categories,
the M90 EXEC always loads the executable file from the RAM/ROM into
the RAM executive area. It then begins execution.
Workstation mode is the default resident M90 Operation. In workstation
mode, an M90 configures as a portable programmable device. The system
receives transient application programs from the host using a download
channel. The system also receives the resident application, from ROM.59
programs or data files, that can reside on an M90. Up to eight resident ap-
plications can reside on an M90. The operator can then select one of the
applications using the keypad host command sequence.
The transient application operates as a file and purges when the M90 per-
forms a cold start. While File Manager does not support the resident ap-
plication, it is always in ROM.
Data files or recorded information collected from workstation applications
are uploaded to the host when the host program decides to retrieve the col-
lected data. Some applications may also require prepared data files, such as
database information. These data files are loaded into the M90 in the same
way that the program is downloaded.
When the M90 is in User Mode, the user menu is displayed. The operator
may select one of the following functions:
S RUN
Runs executable program
S TER Terminal mode operation
S COM
Communicates in Kermit protocol
S DIR Displays M90 RAM disk directory
S ERA Erases file
S TYP
Types file
S CPY Copies file
S SET Sets M90 Parameters
Use host communication commands to perform all keypad controls.
Note: If the M90 Communication Parameters are not set correctly, the
host system cannot send any control commands.
