When monitoring serial communications between two devices, Docklight cannot control the amount of incoming data. Since Docklight applies a number of formatting and conversion rules on the serial data, only a limited number of bytes per seconds can be processed. There are numerous factors that determine the processing speed, e.g. the PC and COM devices used, the Display Settings, and the Receive Sequence Actions defined. It is therefore not possible to specify any typical data rates.

The most time-consuming task for Docklight is the colors&font formatting applied by default (see the Docklight Display Options). If Docklight cannot keep up with formatting the incoming data, it will automatically switch to the simpler Plain Text Mode.

If this is still not fast enough to handle the incoming data, Docklight will add the following message in the Communication Window output and log files.

DOCKLIGHT reports: Input buffer overflow on COM1

TIP: Search for this message using the Find Sequence in Communication Window... (Ctrl + F) function.

If you are experiencing the above behavior, Docklight offers you several ways to increase the data throughput.

1.	Simplify the display output:

- Deactivate all unneeded Display Modes in the Options... dialog

- Use Plain Text Mode right from the start (see the automatic switch behavior described above).

- If you are using ASCII mode, disable the Control Characters Description option

2.	Log the communication data to a plain text file instead of using the communication window(s):

- Use the "plain text" Log File Format

- Create only a log file for the Representation (ASCII / HEX / Decimal / Binary) you actually need

- Disable the communication windows while logging, using the High Speed Logging option

Use the Communication Filter from the
