| 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: | |

| 52 | The entire telephone number must be | |
| 53 | presented in a single | |
| 54 | .I write | |
| 55 | system call. | |

| 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. |
