I received a new Alinco DR-135TP for Xmas from my brother. The TNC is integrated into the rig. I have followed the skimpy instructions in the manual by connecting an RS-232 cable from my 135TP to my computer. When I boot up the computer it does not see the radio. What am I missing here? What do I need to do next? I am using a US Robotics external modem on the computer that is hooked to serial port com 2. I have set Com 1 at 9600 baud and data length 8 bits, parity none, Flow control to Xon/Xoff as per the manual but how do I set up the EJ-41U (the internal TNC)? Any help will be greatly appreciated. Thanks and 73's

For starters, disconnect the ext. modem temporarily and see if you can set up the TNC on COMM Port 2.  That will tell you if it's a COMM Port problem or not.  THEN, if it still doesn't work, look at a serial interface cable problem.  There are all kinds of wiring variations for serial cables, and that could be a problem.  Of course, there COULD be a problem with the radio, but I think that's the least likely scenario.  If you can substitute a different cable, I'd try that first, or use the modem cable from COMM Port 2 to connect to the radio and see if that works.
    Does the radio manual describe the type of serial cable needed, or better yet, give a wiring diagram?
    Lastly, you can ask these questions of the Customer Service Dept. for the radio.  Good luck!
