I opened up a windows hyperterminal at 57600-8-N-1 and the rig responded to a "?V" with "VER 1180-538" Tried the "?A" to see VFO-A and it returned some binary info (ASCII garbage). So would one of the skilled programmers out there please write a CAT interface for the JUPITER? looks like we are no longer out of the picture for rig control. dit dit de ken n9vv
