AT&T has this nice (relatively) new phone which comes with a DB-25 connector and a built-in modem. DEC has a (kind of) new, asymmetric, 6-conductor connector used in most of their recent small computers' and workstations' serial ports. Both RS232 and RS422 standards are supported. They call it DEC423. I recently went through the process of making these devices talk to each other, specifically for a host computer that receives incoming calls. It is very straightforward, except if you want what I call the 'complementary features': the computer should automatically log you out if the call is lost and conversely, the modem should hang up whenever the user logs out. Since there are a couple of tricky steps, such as making a few changes to both hardware and software, I can E-mail specific instructions to anyone interested. Please reply via E-mail. Ramon F.
