10 | rv \- Racal/Vadic ACU interface | |
11 | .SH DESCRIPTION | |
12 | The racal/vadic ACU interface is provided by the files | |
13 | .I /dev/cua[01] | |
14 | which is a multiplexed file, and by the daemon | |
15 | .I dnd | |
16 | which monitors the file, simulating a standard DN dialer. | |
17 | To place an outgoing call one forks a sub-process | |
18 | trying to open | |
19 | .I /dev/cul? | |
20 | and then opens the corresponding file | |
21 | .I /dev/cua? | |
22 | file and writes a number on it. | |
23 | The daemon translates the call to proper format for the | |
24 | Racal/Vadic interface, and monitors the progress of the call | |
25 | recording accounting information for later use. | |
26 | .PP | |
27 | The codes for the phone numbers are the same as in the DN interface: | |
28 | .TP | |
29 | 0-9 | |
30 | dial 0-9 | |
31 | .br | |
32 | .ns | |
33 | .TP | |
34 | .B : | |

38 | .TP | |
39 | .B ; | |
40 | dial # | |
41 | .br | |

50 | end-of-number | |
51 | .PP | |
52 | The entire telephone number must be | |
53 | presented in a single | |
54 | .I write | |
55 | system call. | |
56 | .PP | |
57 | It is require that an end-of-number | |
58 | code be given. | |

74 | .PP | |
75 | The multiplexor seems to have rare-case bugs which occasinally crash | |
76 | the system taking trap type 9's, usually in the | |
77 | .I sdata | |
78 | system routine. |
