/* 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. */
