| Configure a unit for each port to be tested. The protocol
should be set to LOOPBACK and the port set to the required baud
rate etc.
|
| 2.
|
The following CITECT.INI options are supported:.
|
|
|
[loopback]
|
|
|
loopback = 0 or 1
|
|
|
Set loopback to 1 if internal loop back is to be performed
(make sure this entry is deleted after running the loop back test).
With loopback set to 0 ,a loop back connector which ties pins 2 and
3 together is required at each port.
|
|
|
size = maximum frame
size
|
|
|
Set the maximum frame size to 'size'. The length of each frame
transmitted is random between 1 to size - 1. The default size is
512.
|
| 3.
|
There should be no other drivers configured.
|
| 4.
|
Start up citect. Each port will transmit a frame of random
length. This process is repeated when the entire frame is
received.
|
| 5.

Use "page driver" in the kernel page to look at the statistics.
Type 'v' to set to verbose mode. The following statistics are
displayed:
|
|

|
|
|
Start time in milliseconds.
|
|
|
Total number of errors.
|
|
|
