What kind of RS232 problems have you previously had, and/or currently have? RS232 here can be read to mean many things. For example in the following list I mention dropping a laptop.

I can not do this with checkoff boxes so a written response is necessary. Define your machine, control, and application.

Some example areas of problems:

1. Cable length
2. Transmission data errors
3. CNC's maximum baud rate is too low
4. Have to operate at a baud rate lower than CNC machine's maximum capability
5. Ground loop noise causing errors
6. Noise generated within the CNC causing transmission errors
7. CNC is starved for data in drip mode (DNC) on short strokes
8. Circuit damage from elcectrical storms, or electrical faults, or ground problems
9. Pinouts for wiring computer to CNC
10. Lack of understanding how RS232 works, and related problems
11. Sending multiple files from computer to CNC
12. Noise from welders or plasma cutters
13. Difficulty of putting CNC in send or receive mode
14. Time out problems
15. CNC Program file management
16. Having to go back and forth between computer and CNC
17. Need to run CNC programs larger than available memory in the CNC
18. Need to do simultaneous drip feeds
19. Damaging your laptop because you dropped it
20. Format of file being sent to CNC is not accepted by CNC
21. Handshake problems
22. Need for delays between CNC program blocks
