Programming with SPM

Figure 2-6. Pass-Thru

A Pass-Thru request must be initiated by a DOS PC. It is not available from a
UNIX system PC; that is, Pass-Thru cannot be established between two
IS-II/III PCs.
Once your Pass-Thru connection is established, you can administer any of the
following IS-II/III applications from your SPM PC:
AUDIX Voice Power™
Call Accounting System
Fax Attendant System® (IS-III only)
CONVERSANT® Intro (IS-III only)
NOTE:
You cannot administer the SPM application on the IS-II/III PC because the
remote call (from your SPM PC) uses the IS-II/III PC's COM1 port, so the
system programming jack cannot be used for system programming, For the
same reason, a user at the IS-II/III PC end of the connection cannot use
SPM while your Pass-Thru is in effect. If use of SPM is attempted, the user
at the IS-II/III end sees this message:
PRE-EMPT IN PROGRESS
Please try again.
To initiate Pass-Thru, establish a modem connection between the SPM PC and
the control unit.
If the lS-II/III PC does not respond to the Pass-Thru request from the control unit
(for example, because the PC is turned off), you see the following message;
Pass–thru failed.
Please try again.
