The problem is the new Win2000 PC is running faster and the communication port is probably different.
Check the FIFO settings on the COMM Port and make sure this is set to LOW or disabled. Also maybe try a line delay in transfering the file. This is probably a setting in the Easy Talk software.
Need more help, give me a call and maybe we can help...we dont sell Easy Talk but have lots of experience with PCs and CNC communications.
