Fine. I used it like that for several years, both modem and ISDN. In fact the reason I ended taking over diald from Eris was because there were some things that needed to change to handle double ended demand dialling. In particular, pay attention to the died-retry-count option. If both ends can demand dial you want to set this to 0 so that the link is _only_ brought up if there is traffic. The default is 1, which tells diald to assume that the other end is dumb and that if the link goes down while diald has active connections it must bring it straight back up again (even if no packets are currently flowing) because the other end won't even if it has packets to send. The default is fine for ISP type links but if both ends demand dial it leads to links that bounce up and down and up and down and ... Mike
