21/* Extensions made by Werner Cornelius (werner@ikt.de) */
22/* */
23/* The proceed command holds a incoming call in a state to leave processes */
24/* enough time to check whether ist should be accepted. */
25/* The PROT_IO Command extends the interface to make protocol dependent */
26/* features available (call diversion, call waiting...). */
27/* */
28/* The PROT_IO Command is executed with the desired driver id and the arg */
29/* parameter coded as follows: */
30/* The lower 8 bits of arg contain the desired protocol from ISDN_PTYPE */
31/* definitions. The upper 24 bits represent the protocol specific cmd/stat.*/
32/* Any additional data is protocol and command specific. */
33/* This mechanism also applies to the statcallb callback STAT_PROT. */
34/* */
35/* This suggested extension permits an easy expansion of protocol specific */
36/* handling. Extensions may be added at any time without changing the HL */
37/* driver code and not getting conflicts without certifications. */
38/* The well known CAPI 2.0 interface handles such extensions in a similar */
39/* way. Perhaps a protocol specific module may be added and separately */
40/* loaded and linked to the basic isdn module for handling. */
