These are the packages that would be merged, in order: |

Calculating dependencies... done! |

#rc-update add apcupsd default. So far so good. |

But when I try dialup I get this: |
| 34 |
|
| 35 |
Device ttyS0 is blocked by PID 3981 |
| 36 |
|
| 37 |
which turns out is apcupsd. So I have to kill it before I can dial out. |
| 38 |
Sure enough, in the conf file there is this: DEVICE /dev/ttyS0. |
| 39 |
|
| 40 |
Which makes me wonder why it needs /dev/ttyS0? I'm using an external USR modem which uses ttyS0. |
| 41 |
|
| 42 |
If I don't need to protect a fax-machine why do I need that phone line connector in the back of the UPS device anyway? When the power goes I don't care if the modem dies. |
| 43 |
|
| 44 |
Can I just tell it to use one of these other /dev/ttyS*? If I comment out that DEVICE line will the thing still protect my PC? |
| 45 |
|
| 46 |
heathen@localhost ~ $ ls /dev/ttyS* |
| 47 |
/dev/ttyS0 /dev/ttyS1 /dev/ttyS2 /dev/ttyS3 |
