I have looked at the c3270 and I will try it as soon as I get pdaxrom version 1.0.5 to accept my Sandisk CompactFlash 802.11b card. I have used x3270 and c3270 both under Linux and Windows (Cygwin) and they function perfect for my needs. But the x3270 is first choice. and it would have been nice also to be able to use it on the Z !
Anyway thank you for your answer!
