This page lists the diagnostic log records.
The Save Cellular Network Traffic selection saves cellular network traffic to the filesystem.
If this option is enabled, the output goes to ppp-YYYY-MM-DD_HH.MM.pcap.
YYYY-MM-DD_HH.MM is the time at which capture was started.
The Output selection optionally directs logging to the filesystem or to a serial line. If Filesystem is selected, the output goes into /log.txt.
Use Max Length to limit the size in Kbytes that /log.txt will be allowed to grow to. If this size is exceeded, the file will be reinitialized using the 100 most recent messages.
The Verbosity Level field is used to specify verbosity of system message logged to the Syslog Host.
The "Cellular Modem IO" field is used to enable or disable logging of commands and responses with the Cellular Modem.
