Description
Charon stores the console (SRM console) parameters in specific files (*.rom, *.bin, *.dat) belonging to ROM and TOY emulated devices. If Charon is upgraded those files are usually re-created, so the parameters they store get lost.
| Info |
|---|
This is not the case when upgrading Charon-AXP and Charon-VAX starting with version 4.8 (so examples: upgrades from 4.8 to 4.9, 4.8 to 4.10 or 4.9 to 4.10, etc...). In this case console parameters are kept. |
...
| Note |
|---|
Each Alpha and VAX model has its own set of console parameters and syntax of console commands. This Application Note describes most useful and typical of them. For more details please refer to corresponding User's Guide for your Alpha/VAX system. |
