*
|
||||
* ------------------------------------------------------------
|
||||
* This is from the manpage of isdninfo(4):
|
||||
*
|
||||
* DESCRIPTION
|
||||
* /dev/isdninfo is a character device with major number 45
|
||||
* and minor number 255. It delivers status information from
|
||||
* the Linux ISDN subsystem to user level.
|
||||
*
|
||||
* DATA FORMAT
|
||||
* When reading from this device, the current status of the
|
||||
* Linux ISDN subsystem is delivered in 6 lines of text. Each
|
||||
* line starts with a tag string followed by a colon and
|
||||
* whitespace. After that the status values are appended sep-
|
||||
* arated by whitespace.
|
||||
*
|
||||
* flags is the tag of line 5. In this line for every driver
|
||||
* slot, it's B-Channel status is shown. If no driver
|
||||
* is registered in a slot, a ? is shown. For every
|
||||
* established B-Channel of the driver, a bit is set
|
||||
* in the shown value. The driver's first channel is
|
||||
* mapped to bit 0, the second channel to bit 1 and so
|
||||
* on.
|
||||
* ------------------------------------------------------------
|
||||
*
|
||||
* So we open /dev/isdninfo, discard the first four lines of text
|
||||
* and then check whether we have something that is not `0' or `?'
|
||||
* in one of the flags fields.
|
||||
*
|
||||
* Sounds complicated, but I don't see any other way to check whether
|
||||
* we are connected. Also, this is the method some other ISDN tools
|
||||
* for Linux use.

||||
