| Modification history: | |
| 25-Jan-13 RJ SELFTEST needs to report the READY state otherwise VMS 3.7 gets fatal controller error | |
| 23-Jan-08 MP Added debugging support to display packet headers and packet data | |
| 08-Dec-05 DTH Added load_server, increased UDBSIZE for system ID parameters | |
| 07-Jul-05 RMS Removed extraneous externs | |
| 05-Jan-04 DTH Added network statistics | |
| 31-Dec-03 DTH Added reserved states | |
| 28-Dec-03 DTH Corrected MODE bitmasks | |
| 23-Dec-03 DTH Corrected TXR and RXR bitmasks | |
| 03-Dec-03 DTH Refitted to SIMH v3.0 platform | |
| 05-May-03 DTH Started XU simulation | |
