I am trying to connect to my TT4 with TeraTerm (latest version).? It shows me three options to connect to.? One seems to be a RT Systems Cable.? That can't be the right one, can it?? I connect to it but only get a black screen.? I seem to remember from several years ago that I had to put TeraTerm into a special command mode by quickly pressing escape three times or something but for the life of me I can't seem to get that right.? There are two other options offered when I go to connect.? One is Com 5 and one is Com 6.? Sometimes it will connect and sometimes it won't.? I am trying to connect at 1200 baud which is what the radio is set at.? Is that the correct baud rate?? Can someone walk me through how to do this.? I am trying to tune the RX AMP on the TT4 for an iGate installation on a new radio.? The radio is a Yeasu FTM400 XDR and the PC is a newish Windows 11 PC.? Maybe two years old.? Latest Windows updates installed.? Connection to the radio is through the MIC and SPKR jacks as the data jack won't transmit on APRS and there is no cable manufactured for the data jack by the TT4 folks.? Thanks!
