RE: xioc3270tn emulator?

[a.vi...@yahoo.com]

I went to my bank and my clerk had a Windows 2000 workstation. She
brought or
"connected" this terminal emulator from her Windows 2000 which I leaned
over and
I noticed at the top it said: xioc3270tn. And at the bottom of the
emulator it
said:

"CWS/230/zos/".....What does this mean by the way?

Now, can she be using a X-Windows server on the Windows 2000
workstation to
connect to the Mainframe using that xioc3270tn emulator?

But I dont understand how or where the UNIX comes into play. First you
have to
use UNIX to bring up the xioc3270tn emulator and then connect to a
Mainframe
running CICS on z/OS using that xioc3270tn emulator?

I hope this is the right topic for this area. If not, please direct to
a right
frum area were peopke can better explain this to me please.

I would appreciate it please.

Thanks in advance!!
