hi everyone!
i am doing a modem communication for a telephony design. we decided to use the v.22bis protocol for modem comm. on my observation, when working at 2400b/s, after handshake , there will be stream of garbage seen on the hyper terminal. so my tx and rx is definitely out. but very clean when doing 1200b/s. tx and rx of data is ok.
may be it is something to do with the telephony board design.it must have created some noise that would interfere the comm at 2400b/s. because when i test from ext. modem to another ext. modem, it is ok at 2400b/s.
hopefully someone could give some input or ideas. thank you very much for any reply!
rgds,
elin
