SECTION 6. SMCOM
SMCOM is used to collect and store data and/or programs from the SM192 and SM716 Storage
Modules. It runs on an IBM PC/XT/AT compatible computer. SMCOM communicates with the Storage
Modules through an asynchronous communications adapter at 19,200 baud.
A hardware interface is required, this is either the SC532 Storage Module Interface or the PC201 Card
with the SC209 cable. An older interface, the SM232 or SM232A can also be used; to use one of these
interfaces, start SMCOM by entering SMCOM SM232A on the command line.
6.1 GETTING STARTED
Enter 'SMCOM' on the command line to load
and execute the program. The PC must be
logged onto the current drive and directory
containing SMCOM or the appropriate "path"
must be specified. SMCOM will prompt:
SMCOM Ver X.X

Serial Port Options:
1 -- Com1
2 -- Com2
3 -- Com3
4 -- Com4
Option:
Enter in the appropriate number for the
communication port that you are using.
SMCOM immediately establishes
communication with the Storage Module and
puts a status window at the top of the screen.
The status will be updated automatically when
changes are made.
If the proper communication is not established,
SMCOM aborts, and gives the message
SM192/SM716 Storage Module does not
respond! Reducing baud rate...
If this happens, verify that all cables are
connected properly and that the proper COM
port was specified.
If SMCOM establishes communication but the
status lines at the top of the screen are not
visible see section 6.6.
6.2 SMCOM OPTIONS
The SMCOM OPTIONS menu appears as soon
as SMCOM establishes communication with the
Storage Module. The options will be displayed
as follows:
SMCOM Options:
T -- Terminal emulator.
A -- Collect all data files.
U -- Collect uncollected data files.
N -- Collect newest data file.
L -- Collect one data file starting at
display pointer L.
P -- Collect program files.
D -- Store a .DLD program file.
F -- Store a file.
E -- Erase and Reset Storage Module
C -- Clear Data Area
S -- Switch Settings
Q --Quit
Option:
To select an option, key the appropriate letter.
When one of the "collect" options is selected,
SMCOM will ask for a file name and storage
format. These topics are discussed in Sections
6.3 and 6.4. A description of each option
follows.
6.2.1 T -- TERMINAL EMULATOR
The T option allows the user to communicate
directly with the Storage Module. This option is
provided to allow users to manually issue
Storage Module telecommunication commands.
Keying F1 while in Terminal Emulator will
display a list of Storage Module commands.
This option is seldom used because all normal
operations can be accomplished by other
selections from the options menu. Keyboard
entries are transmitted out of the COM port to
the Storage Module and Storage Module
responses are displayed on the computer
