5341.0. "%CLI-E-TRMMBX when spawning from TN3270" by GIDDAY::TAN () Mon Mar 17 1997 01:14

	A customer is running UCX V4.1 ECO3 on an AlphaServer (but
the problem is believed to appear on earlier UCX too).  When he did
a TN3270 connection to his IBM/MVS system, he can't spawn out of
the telnet connection, he gets the following message:

TELNET> spawn
%CLI-E-TRMMBX, terminal has associated mailbox - terminate image and then
SPAWN

If he just do a normal telnet, then spawn worked, but he needs the
3271 terminal emulation!

	I tried tn3270 to a VMS system, and was able to spawn out of
the telnet prompt, but then again, I wasn't in the full 3270 terminal
emulation.

	Is this a known problem?  (I don't have an MVS to reproduce
the symptom)

    This is a problem as the TN3270 code uses SMG (this code comes from the
    SNA group).  It uses the terminal's associated mailbox to receive the
    notification of certain events on the terminal.
    
    This is currently a restriction.
5341.2any plan to include in future version?GIDDAY::TANMon Mar 17 1997 21:2010
John,

	Is this restriction documented anywhere?  I need it to fence off the
customer, otherwise, in his own words, "Are Engineering going to resolve this 
problem or do you guys know of any third party product?"

	Thanks,
