i have been working on serial port speed issues
all was fine at 57600 , except for some lockups
i suspect i might have been overusing the serial
port, so i reduced speed in 

vinny210
mach3 modbus config
windows7 device manager com port

to 19200

lockup gone now but output
pin buttons in wizard are very slow
need to be clicked several times
cursing helps also.
use all on and all off buttons to toggle all pins




i am not sure reducing speed was the way to go if
problem was caused by reading/writing to much data.
will post update when i figure out what up.
