Ross) Organization: The MITRE Corporation, Bedford, MA. Lines: 23 Keywords: Anderson Jacobson Summary: What makes it transmit a carrier? I am looking for information about my Anderson Jacobson (model AJ1234) modem. It has both an acoustic coupler and a direct connection ability, but it does not seem to respond to a Bell 212 answer carrier. I am hoping someone can find a user's manual for this anchor, or perhaps just tell me what this thing is. I'm not sure what signal states it wants on the RS232 port or what connections can be made to its "DAA/DIRECT" connector (has six large pins in a row). I tried playing with the control lines on its RS232 port using a breakout box but could not get the thing to communicate. I would like to know if this thing is not working or if I'm just not using it correctly. It has switches inside to select baud rate (1200 or 600 bps), parity, bits per symbol, carrier frequency (1200, 1205, or 1225 Hz), synchronous or asynchronous mode, and transmit/receive power levels for direct connection. Any information, suggestions, or especially a user's manual would be very helpful. Thank-you... -- Gordon W.
