No. You don't have to do this. It has some special functions (you can get it to initiate calls by using this button). You'll probably never use it. >The data sheet says that there is an RJ45 line connector. >Questions 2: I *thought* phones used and RJ11 connector.

They supply appropriate cabling. Yes, there are two plugs. >Question 3: Does the T2500 work well with the MacOS and A/UX 2.0? Yes.

It depends upon how smart/stupid your telecom app is. Certainly, it take more juice to move bitmaps around than it would for character-based stuff. Cu works OK, though. >In reguards to A/UX and cu, It appears to me that Apple has hardwired >in the ATD command (the fourth entry in the L.sys entry for a system >gets prepended with an ATD and sent to the modem).

Anyway, you can always say "dir" at the end of the cu to just grab the modem without dialing anything. >Tip seems to add slightly more functionality than cu, however I have >not been able to get tip to work at 2400 baud with the Practical >Peripherals modem. (1200 baud worked fine). Have you created the appropriate entry for 2400bps operation in all the right places?
