System Programming and Maintenance (SPM) for the MERLIN LEGEND
Communications System is a DOS-based software application that allows the
use of a PC for programming and maintaining the-system. SPM performs the
same functions as an MLX-20L telephone used as a system programming
console and has some additional features, such as the ability to back up and
restore files and print reports. The PC display shows the same button and
screen layout as an MLX-20L telephone.

SPM operates with DOS, version 3.3 or later.
Unless the system is being backed up or restored, a remote user takes
priority over a local user. If the local user is programming when a
remote user connects to the system, the system sends a message to
the local user that a remote connection has been made and
disconnects the local user.
The PC with SPM connects to the EIA-232-D jack on the processor of
the control unit. The EIA-232-D baud rate is 1200/2400 bps with auto-
baud adjust.
A printer connected to the PC with SPM can be used to print system
programming reports. Or reports can be sent to the printer that is
connected to the SMDR port on the control unit.
SMDR information may be lost while system programming reports are
printed via the SMDR port.
A UNIX-based version of System Programming and Maintenance is
available as part of Integrated Solution III, as discussed earlier in this
chapter.
