-/* Extensions made by Werner Cornelius (werner@ikt.de) */
-/* */
-/* The proceed command holds a incoming call in a state to leave processes */
-/* enough time to check whether ist should be accepted. */
-/* The PROT_IO Command extends the interface to make protocol dependent */
-/* features available (call diversion, call waiting...). */
-/* */
-/* The PROT_IO Command is executed with the desired driver id and the arg */
-/* parameter coded as follows: */
-/* The lower 8 bits of arg contain the desired protocol from ISDN_PTYPE */
-/* definitions. The upper 24 bits represent the protocol specific cmd/stat.*/
-/* Any additional data is protocol and command specific. */
-/* This mechanism also applies to the statcallb callback STAT_PROT. */
-/* */
-/* This suggested extension permits an easy expansion of protocol specific */
-/* handling. Extensions may be added at any time without changing the HL */
-/* driver code and not getting conflicts without certifications. */
-/* The well known CAPI 2.0 interface handles such extensions in a similar */
-/* way. Perhaps a protocol specific module may be added and separately */
-/* loaded and linked to the basic isdn module for handling. */

+ * pulled out of a hot-pluggable slot).
