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. */ |
