[Elecraft] K2 - KIO2 stop bit oddity

[Joe Planisky]

Hey Folks,

I've just finished assembling a KIO2 for my K2 (SN 3490, Firmware  
2.04).  It seems to be working, but it only works reliably when I set  
my terminal software to use 1 stop bit instead of 2.  If I set my  
terminal to 2 stop bits, I get garbled data about 70% of the time.   
For example, the ID; command will return ID017, ID0, ID, ID01, etc.   
I've observed this behavior on both a Mac and a PC, so I don't think  
it's my terminal program.  I tried the MacK2 program and it works  
extremely erratically, presumably because it assumes 2 stop bits.  The  
KIO2 manual says to use 2 stop bits, but that 1 stop bit will also work.

Before I dive into this, I thought I'd see if anyone else has  
experienced this problem.

Thanks in advance for any advice.
