Question:
When I try to connect to the Virginia Tech Modem Pool in Windows XP/Vista, I get the "line is busy" error message. How do I fix this?
Answer:

Depending on whether you receive the "line is busy" error message occasionally or constantly, you will need to follow the appropriate steps:
  • If you receive this error message occasionally, it means the terminal server is full, and there are too many computers already connected. If this is the case, try to connect again at another time.
