[ Web Can ] Visually Indicate when a message is wrong and why

[kammce]

• On input field change for the bytes, color it red if it is outside of the hexademical character set
• When more than 2 character are filled into a byte section, the focus is transitioned to the next byte in the chain. If at the end of the chain of enabled data_X fields, stop changing focus.
• Add the mistaken entry into the output table but with strike through in order to indicate that it wasn't sent. May also be good to color the entry a grey'ed out grey as well.
• Make a system bell sound when an invalid input is attempted to be sent.
• Change the color of the message ID if it is beyond what is possible for the ID value
