Hi all, I was hoping someone might have some good suggestions on implementing a 2400baud modem - V.22bis. Due to size and cost restrictions, I am trying to get a PIC16C505 to act as a data rate converter (from 300 to 2400 baud) through a TDK 73K224L data pump. So far FSK mode has been implemented but have not had much luck with either the 1200 or 2400 baud originate sequence. I have looked up the TDK ref, but to my dismay have found the data to be conflicting and confusing. If anyone has any information or good sources, please advise. Many thanks. Sincerely John Orhan
