Debug parameters for mISDN_core.ko :

#define DEBUG_SOCKET 0x00000004
#define DEBUG_MANAGER 0x00000008
#define DEBUG_SEND_ERR 0x00000010
#define DEBUG_MSG_THREAD 0x00000020
#define DEBUG_QUEUE_FUNC 0x00000040
#define DEBUG_L1 0x0000ff00
#define DEBUG_L1_FSM 0x00000200
#define DEBUG_L2 0x00ff0000
#define DEBUG_L2_FSM 0x00020000
#define DEBUG_L2_CTRL 0x00040000
#define DEBUG_L2_RECV 0x00080000
#define DEBUG_L2_TEI 0x00100000
#define DEBUG_L2_TEIFSM 0x00200000
#define DEBUG_TIMER 0x01000000
#define DEBUG_CLOCK 0x02000000
e.g. load mISDN_core with Layer1/Layer2 debug messages via
modprobe mISDN_core debug=0x00ffff00
on Debian systems get logs from syslog via
tail -f /var/log/syslog
every mISDNv2 Layer1 driver can process debug module param, too.
/*
* HW DEBUG 0xHHHHGGGG
* H - hardware driver specific bits
* G - for all drivers
*/
#define DEBUG_HW 0x00000001
#define DEBUG_HW_OPEN 0x00000002
#define DEBUG_HW_DCHANNEL 0x00000100
#define DEBUG_HW_DFIFO 0x00000200
#define DEBUG_HW_BCHANNEL 0x00001000
#define DEBUG_HW_BFIFO 0x00002000
e.g. via
modprobe xhfc_su.ko debug=0x3FF
o check what driver custom debug flags are available, you have have a look into the sources, e.g. xhfc_su.h
the user tool misdn_log provides on-the-fly D/E-Channel Logging to monitor Layer1/Layer2 Traffic.
