Well, I may of messed up. Last night I burned in the new Eprom image for the WA4DSY modem using the Edit56k windows utility and an older JTR Eprom programmer. Thinking standard serial lines, In the excitement, I did not hesitate to unplug the modem from the PackeTwin card while the machine was running. This I had done zillions of times with the standard serial kiss links. After burning and installing the new Eprom I hooked everything back up and rebooted the system. Much to my dismay the PackeTwin card does load but it does not talk to the WA4DSY modem anymore. It appears that I may have blown away the RS-422 chipset. I replace the original Eprom and had the same results. Looks like I am out another $36.00 for a chipset. Hopefully this msg may save someone else the expense. Comments always welcome. regards, John :-(
