Summary: Error when T#, M6 in different MDI commands

Initial Comment:
(CVS TRUNK, 2008/12/21)

Under certain circumstances, issuing "T#" and then "M6" in MDI mode lead to the 
error "Need tool prepared -Txx- for toolchange".

0. Use configs/sim/axis.ini.  F1 F2 ctrl-home F5
1. In halcmd, "unlinkp iocontrol.0.tool-prepare" to disconnect the tool-prepare 
loopback
2. In MDI, issue T1
 (at this point, observe that tool-prepare is TRUE and tool-prepared is FALSE)
3. In MDI, issue M6

Expected result: emc remains paused waiting for the tool prepare to complete.  
When it is completed by setting tool-prepared TRUE, the tool change should 
occur.

Actual result: An operator message "Need tool prepared -Txx- for toolchange" is 
shown.

This error presumably occurs on real machines where "prepare" takes time and T# 
/ M6 are issued as separate MDI commands.

It doesn't seem to affect AUTO mode.
