| <h1>Message file details</h1> | ||
|
|
||
| <h2>Introduction</h2> | ||
|
|
||
| Since version 1.6 dsdccx has the capability of sending regularly the traffic status messages to a file using the `-M` option. The `-m` option specifies the rate at which the information is polled and written to file. It is expressed in seconds at a 48 kS/s rate and has a minimum value of 0.1s. At 0.1s it will poll everu 48000*0.1 = 4800 samples. | ||
|
|
||
| The polling period will match an actual time interval only during live operation when samples are fed from a real device although buffering might alter this. | ||
|
|
||
| <h2>File format</h2> | ||
|
|
||
| There is one line per polling occurence with a fixed format depending on the protocol. For all protocols the line starts with a timestamp and a protocol identifier. Details by protocol are given next. | ||
