4 | * more than one platform will want to use it, but not part of the |
5 | * main configuration. The expectation is that each platform's |
6 | * local config function will call out to ser_setup_config_box() if |
7 | * it needs to set up the standard serial stuff. (Of course, it can |
8 | * then apply local tweaks after ser_setup_config_box() returns, if |
9 | * it needs to.) |
