COURIER HIGH SPEED MODEMS
| When you power on the Courier, it loads the settings stored in |
| NVRAM if DIP switch 10 is OFF. Until you write your own |
| settings to NVRAM, the defaults stored there are the same as |
| the permanent ROM factory settings stored in position 1, &F1. |
| To view the &F1 settings, select option 5 of the I (inquiry) |
| command: |
| AT I5 <Enter> |
| Customizing NVRAM |
&W | To substitute a template other than &F1, write the desired |
| template to NVRAM, using the &W command. |
| AT &F2 &W <Enter> |
| To modify the &Fn configuration in NVRAM, type your |
| changes and then save them to NVRAM, as in the following |
| example. The original factory template remains intact. |
| AT M2 S10=40 &A2 &W <Enter> |
| NOTE: When writing a different default configuration to |
| NVRAM, insert any additions after the &Fn command but before |
| &W. Otherwise they will be overwritten by &Fn. |
| After sending a configuration to NVRAM, you can change any |
| setting just for the current session, as in the following example. |
| The NVRAM configuration remains intact. |
| ATX6 <Enter> |
| But if you want the new setting to be a default, write it to |
| NVRAM at the same time, as in the following example. X7 is |
| substituted for the Xn value stored earlier. Any other setting |
| that was changed and can be saved to NVRAM will also be |
| saved. |
| AT X7 &W <Enter> |
