Here are some of the latest things that I have learned (so of it the hard way) that may help others. I am at a point where I now can hear the mountain top and decode the input data stream. This is forwarded to the jnos console as-well-as the ax25-utils MH listing. I had to do a couple of things to correct the misunderstanding about the PackeTwin interface card and the DSY modem. I had to change the NRZI to a 0 in the dmascc_cfg. Dale Heatherington mention that the modem already does the NRZI conversion. My DMA port is DMA = 3 This was due to my Sound Blaster using DMA 1 & 5 I found some mis-crimped connections on the PackeTwin ribbon cable that is used for port A (factory defect). This was discovered while ringing out the serial sync line from the PackeTwin ribbon cable to the modem interface connector. Now, if I can just get the mountain top to hear me. I have traced the RS-422 TD +/- signals all the way to the 26SL32 chip on the modem and every thing looks good. So close, but no cigar, yet, hi. I am curious if anyone else is using 56k baud on the list. If so what are the TXDelay, Slottime .... params that they are using ? Regards to ALL, John
