Hmmm... that's odd. I presume you are using the Serial_TNC port type to communicate with your PK88. It sounds like the PK88 is upset that it is not getting proper modem control signals for hardware flow control. Did you check that option (TXFLOW or XFLOW) on the PK88? Also, you should be in KISS mode (per the directions in the PK88 manual, though I'm not sure about the HOST ON command). And you definitely don't want to have HPOLL ON specified on the PK88 (only HPOLL OFF). Also, if you are using hardware flow control, your computer's serial port has to be capable of sending those modem control signals. Many cheap USB-to-RS232 adapters only provide the Signal Ground, Rx Data, and Tx Data signals, and none of the modem control wires (even if the chip inside the adapter supports them) to save on the extra signal voltage level converters. You might want to get an RS232 line monitor box (a cheap one with just line-powered LED indicators) to confirm the hardware flow control signals (CTS, RTS, and possibly DTR and DSR and DCD) are present instead of disconnected. Then ensure you have selected hardware flow control in your YAAC port configuration.
Hope this helps.

I was using putty and the TNC commands to do that. I decided to experiment with objects, so I installed YAAC and configured. I can get my station beacon, messages, and a couple of objects out, but the received packets don't show in the raw packet sniffer. I have made sure there are no filters that would restrict the packets (I never set any up anyway.) When I look at my port config and click the test port button, raw packet data cascades through the black window. After a while, the MULT LED on the PK88 starts flashing which indicates a full receive buffer. I can click test port and empty the buffer, then again after a while, it starts flashing again. I would like to see the map populate with the packet traffic, but that's not happening. Any ideas? Thanks, David KD4ADC |
