How Serialtest Async Taps the Circuit To interface with a serial communication link, connect
serial ports on the PC running the Serialtest Async software to the cable supplied.
 How Spy Taps
the Data Circuit
Spy is a
software-only component of Serialtest Async that monitors the
serial ports on the PC the software is loaded on. It requires no cables or other
hardware.

Data Flow Analysis
View details associated with data traveling between two devices, both data bytes and
control signals, on the Event Display Window. The information displayed for each
data byte includes timestamp,
control signal states, and line errors. Each
byte value is displayed in hex, decimal, octal, binary, and either ASCII, EBCDIC, or
Baudot. The Event Display Window  also calculates the delta time between a selected
range of events. Multiple Event Display windows can be opened simultaneously to allow
users to view different sections of the captured data. |
Byte Level Search
Examine and search data as it is being captured (or after it has been saved), through use
of the Find Function . Use the Find Function to quickly pinpoint problem
areas in the captured data or to move to a specific point in the datastream. Event level
Find Function search criteria include pattern (with bit-level wildcards), time (absolute
or relative), errors, and signal changes. Data searches can also be performed at the frame level. |

Control Signal Status
Examine the real-time status of each major
RS-232 control signal,
DTR,
RTS,
CTS,
DSR,
CD, and
RI, through the Breakout Box Window
.
Counters display the number of state changes associated with each control signal. |
Control Signal Analysis
View the state of each control signal for a defined range of events or over the course of
an entire capture session via the Signal Display Window . Invoking the "Snap To" feature
simplifies problem isolation by causing the cursor to snap to the nearest signal change.
Like all FTS windows, the Signal Display Window and Event Display Window are synchronized;
selecting a range of events on one causes the simultaneous display of the same events on
the other. |

Event Export
The Export feature supports two types of data export: Event
Export and Frame Export. Event Export outputs event level information in text or binary
format. The Event Export function provides output that is human readable, suitable for
importing into a spreadsheet or database, or useable by other programs for
post-processing. Export templates (Excel/Access, comma separated values, etc.) suitable
for this purpose, are included, as is support for the creation of user-definable export
templates. A C++ software program, which demonstrates the use of a simple API capable of
reading a binary export file, is also included. |
Traffic Statistics
Obtain a real-time view of traffic totals
including characters, frames, errors,
characters per second, and percentage
utilization through the Statistics Window . There are three views of the statistics, one for
the entire session, one for the buffer, and one that can be reset at any time. |
