Yes I agree on Daves version it was around the time that VB multi threading was added in. I think his version is single threaded by the way it acts under CB load. That would explain a LOT.
Even on other versions I think the EDS will be better than sendserial.As I understand it it waits in the background for the end of line responce to receive and is always ready to send.
IF coupled to a brain it may reduce the total CB load to do the LCD updates.
It can ALSO run with serial Modbus running.
It should really HELP the older machines that had a serial based tool changer and may also be very helpfull to design a NEW serial based tool changer


Just a thought(;-) TP
