This program will read log files written by -simtrace3-sniff-rx and decode them into slightly-higher-level elements as in -ATR, PPS exchanges, command headers, data transfers and status bytes. +Once you have the log captured, decode it as follows: + +simsniff-dec logfile + +This program reads log files written by simsniff-rx and decodes them into +higher-level elements as in ATR, PPS exchanges, command headers, data transfers +and status bytes.
