Serial Ports
Posted: 15. Jul 2009, 09:19
Hello everyone
I use VB on windows to give me a Linux environment (Ubuntu)
I have set up 2 serial ports and want to use these to communicate with an external device.
Up to a point this works - I can send my device data in chunks of 100 or so bytes and the external device receives them successfully.
However, I need to send chunks a great deal bigger than this and when I try I lose bytes bug time!
I am running on a laptop using USB->Serial converters.
I have elimated the converters as part of the program by running the program on a 'real' Linux machine and also by using Cygwin on my Windows box.
Does anyone know how I can resolve this ?
Thanks
Graham
