Setting Port and Clock Modes
106 Interphase Corporation
When this mode is selected, the text message portion of the
LineTest main dialog displays the following synchronization
results:
Operational Mode
After a test has completed, you must return the port used for
testing to Operational mode so that it can handle incoming and
outgoing communications.
To return the port to Operational mode, select Operational
mode on the Port Test Configuration dialog (shown in
Figure E-2 on page 103).
Before closing the LineTest utility, you are requested to restore
each port in testing mode to the operational mode.
Clock Modes
In some test configurations (such as back-to-back
configurations), a port must use the remote adapter clock to
successfully synchronize on the received signal.
Message Meaning

the port found no errors when comparing
sent and received bit sequences.
X bits in error/sec The port is comparing received bit
sequences with sent bit sequences.
Each erroneous bit found is added, and the
sum is displayed each second.
Not synchronized The port is unable to recognize what it sent.
