When using Ethernet or modem as the transport medium, only Step 1 changes. The
Virtual COM ports are still used to bridge the appropriate application conversation to
the appropriate module within the KTS and back. If a Virtual COM port is not selected
then the associated SPE serial port or PC Application will not be operational.
Certain assumptions are being made when using the SPE ETU module and
application within the context of the KTS.

All four physical serial ports on the SPE can be connected and used
concurrently.
COM4 and COM54 can be used by any of the PC-based applications, such as
SAT, LCR and WSC. Note that because of firmware limitations within the original
MIF(M)-U( ) ETU, only one of these applications can be run concurrently. The
SPE application only allows one of these buttons to be selected.
Multiple applications can now be run over the virtual COM ports to communicate
to multiple modules in the KTS.
The laptop being used does NOT have more than three physical COM ports,
including the modem.
Multiple users are NOT accessing the SPE concurrently using different transport
methods, e.g. one user using the Ethernet and another using Serial. Concurrent
access can result in the SPE(M)-U( ) ETU entering an unstable state since it is
not possible for the firmware to monitor the state of multiple instances of the
same application.
