That's what I thought the OP was doing; it sounds like he's trying to receive 7M1 in Minicom using 8N1 on the terminal and getting garbled data because the high bit is set (because the other end is sending 7M1).  I never meant to imply that 8N1 would give garbled data if both ends were set to it; indeed, that's pretty much standard communications settings for short cables in low to moderate noise environments.  If anyone else read it that way, that's not what I meant. :-)
