| 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 |

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

| 45 | delay for second dial tone |
| 46 | .br |
| 47 | .ns |
| 48 | .TP |
| 49 | < |
| 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. |

| 72 | .SH BUGS |
| 73 | Locking problems. |
| 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. |
