 I have a similar problem using the Tek window with tn3270 in the loop.
 What I mean is as follows:  I use a local xterm to connect to an IBM
 mainframe running VM/CMS with tn3270.  I open up the Tek window and 
 use a locally developed translator (on CMS) to attempt to view a CGM.  

 WHen I tell the translator to view the frame, I get garbage to the 
 Tek window with "TYPEAHEAD BUFFER FULL" messages written all across the
 Tek window.  

 If I use the "same" translator on my workstation, (the UNIX version)
 the Tek window works as advertised. (Note that tn3270 is not in the 
 loop in this case.)

 Under R3, xterm worked in both cases. ( ie.  +/- tn3270)

 Before I installed the first set of fixes, xterm dumped core. With the
 fixes installed, I get the "TYPEAHEAD" messages described above, and no
 core dump.  

 Note that the only thing which has changed in this environment has been
 the upgrade to R4.  The translator and tn3270 versions are the same as
 I used under R3. 

 Particulars:

		  Sun 3/60C
		  SunOS 4.0.3
		  X11R4 with fixes-1

		  built with "cc" (default)

 any guesses?
