[Xastir] Serial port

[Robbie, wa9inf]

Well, here is a follow up to my MFJ serial tnc problem...

I have validated that the hardware is working by using minicom on both 
ttyS0 and ttyS1 at 9600,8,n,1  All the 144.390 packets are decoded..

Now that leaves me with an Xastir problem I guess?? I can not make 
either ports go "up" in the Interface Control screen, :-(

Is there something I failed to do in Xastir while I was installing it?

Thanks in advance,

Robbie
