Can you turn on the DEBUG printing in at.c by changing the following
lines:
#define DEBUG(fmt, ...) while (0) {}
//#define DEBUG(fmt, arg ...) printk("ib_at: %s: " fmt "\n", __FUNCTION__,
## arg);
to:
//#define DEBUG(fmt, ...) while (0) {}
#define DEBUG(fmt, arg ...) printk("ib_at: %s: " fmt "\n", __FUNCTION__, ##
arg);
rebuild ib_at, and send the output of /var/log/messages. Thanks.
