I'm interfacing with the phone line: 1. I need a good number of instructions/sec. Do you think that 16C74 would be ok?? It would be prepared to work with these frecuencies?? What should i have in mind?? 2. Does anybody has info about " TCM 5087 " or " HM 9187 " ?? Does anybody know anything about them?? 3. Anything about phone lines would be apreciated. Thank you very much to you all for helping me. Naish Note: Excuse me about my english. __________________________________ e-mail: naish@euskalnet.net e-mail: jam_naish@usa.net ICQ # 3305163 visit my homepage: http://fly.to/naisaint
