If you don't find a board level solution for the Mac, you can always go with an AT&T 7500 ISDN terminal adapter. These puppies with the right modular option cards can take V.35 sync in/out at 56 or 64 KB. All thats left is to arrange to create the sync data stream from the Mac, and the right `cabling' to get the data into V.35 levels and pinout. The 7500 can also do RS-232 async at 19.2 on one or two serial ports. The only real drawback is autodialing. Since the 7500 is ignorant of what it is you are sending down the 56/64 pipe, it can't interpret any of it for dialing commands. Instead, you have to either manually dial from the front panel, or wire up to the RS366(?) dialer interface. AT&T's also got an older ISDN voice/data telephone that has a V.35 connector. Its the 7514. All dialing is manual with this one. -- Rick Richardson | Looking for FAX software for UNIX ?????? mention PC Research,Inc.| WE'RE SHIPPING your uunet!pcrat!rick| Ask about FaxiX - UNIX Facsimile System (tm) FAX # (201) 389-8963 | Or JetRoff - troff postprocessor for the HP {Laser,Desk}Jet
