63 | /* The proceed command holds a incoming call in a state to leave processes */ | |

67 | /* */ | |
68 | /* The PROT_IO Command is executed with the desired driver id and the arg */ | |
69 | /* parameter coded as follows: */ | |
70 | /* The lower 8 bits of arg contain the desired protocol from ISDN_PTYPE */ | |
71 | /* definitions. The upper 24 bits represent the protocol specific cmd/stat.*/ | |
72 | /* Any additional data is protocol and command specific. */ | |
73 | /* This mechanism also applies to the statcallb callback STAT_PROT. */ | |
74 | /* */ | |
75 | /* This suggested extension permits an easy expansion of protocol specific */ | |
76 | /* handling. Extensions may be added at any time without changing the HL */ | |
77 | /* driver code and not getting conflicts without certifications. */ | |
78 | /* The well known CAPI 2.0 interface handles such extensions in a similar */ | |
79 | /* way. Perhaps a protocol specific module may be added and separately */ | |
80 | /* loaded and linked to the basic isdn module for handling. */ | |
