Stored measured values
Data path delays depend on the link speed and on the NIM (network interface module) type. RX and TX data path delay values are available in the API to allow applications to compensate. The values can be retrieved by an application by using the NtInfo_t structure in the information stream (see DN-0449 for details).
Style Conventions
Bold typeface is used for names of, for instance, user interface elements and software components.
Italic typeface is used for replaceable text.
Monospaced typeface is used for code, commands and file names.
