Chapter 4 - MultiFRAD Software

DLCIs show active at both (or all) locations and there is still an end-to-end communication problem, it

is likely that it is in the configuration of the MultiFRAD. At that point, review your protocol stack/data

port parameters and DLCI mappings.

Data Port Statistics

The Data Port Statistics dialog box displays statistical information, such as bytes or blocks received/

transmitted, for the two data ports.

This window shows the statistics for both data channels. If you highlight and double-click Port 1 or

Port 2 on this screen, you will display another screen of channel statistics and various hardware

signals (RTS, CTS, DSR, DCD, DTR) and Xon/Xoff status. This second screen also displays buffer

utilization percentage and receive flow control time.

These statistics may indicate that either the data channels, or more likely the devices attached to

them, are being driven harder than they should be. Excessive buffer utilization and/or receive flow

control time can usually be reduced or eliminated by slowing the speed at which the channel is

operating.
