Our project is having an issue here and we're not sure how to go about rectifying this error...any help or suggestions will be greatly appreciated!!!
***we encounter an error in this line "public CommPortOpen(Frame F)" which we are supposedly to return F variables but it doesn't, instead the program can't be executed and run properly....question is do we need to change the variable "Frame F" to "null" or do we need to reconstruct this line to another?
It's very hard to read your code. Please use code tags when posting code. You may edit your post using the edit button. Are you able to compile the program? Then, Can you post any stack trace/exceptions arise?
