Com Port Tab

Each Com Port tab represents a specific port you have selected for test and configu-
ration. On the tab, you can see the Transfer Mode, Port Status, and Message Logo
area.
Transfer Modes
You can specify the transfer mode to be Normal, loopback (active) or loopback (pas-
sive).
Normal—allows data to be transmitted and received simultaneously. The data recep-
tion rate is helpful in identifying the performance of a communication card installed on
your system.
Loopback- In loopback mode a series of special data will be transmitted, which are
expected to appear on the receiving end. Using the loopback mode, you can check
the integrity of received data and find whether any error occurred on the transmission
line. The active loopback and passive loopback must work in pair to enable the loop-
back mode. When a port operates as active loopback mode, it will send data first and
