I recently discovered Hylafax, a piece of software that lets you turn a linux box and a fax modem into a fax server. It’s really slick, supporting things like fax printing from windows machines (with a windows client), scheduling, caller id and distintive ring (for incoming calls if your modem supports it). These last two are the ones that have been causing me all the problems. I have a seperate number with a distinctive ring (it comes with the package) and figured I might as well put that to use as a fax number. So I found an old modem that supports both those features (a US Robotics 5686)… at least the box says it does. It took me quite a while to get it to support the distinctive ring. I finally discovered that I had to turn it on (ATS41 = 1) and then save the setting (AT&W0). Once I did that, the modem reported “RING A” for the main number and “RING B” for the second one. Perfect. After that it was easy to tell Hylafax to only answer the second number. What seems to be giving me great fits is the caller ID setting. I found out how to turn it on, but not how to save that setting:
ATZ OK AT#CID = 1 OK RING A DATE = 1018 TIME = 2021 NMBR = XXXXXXXXXX NAME = STEENHAGEN JACO RING A ATZ OK AT#CID? 0 OK
It just goes away as soon as an ATZ gets sent. I’m not sure how to solve that, but I made a newsgroup post hoping that maybe somebody else out there has an answer :).
