I am using Windows 7 on my personal computer (PC). I successfully registered my program with the z/TPF debugger, but the z/TPF debugger session does not start. Why?
The Windows firewall on Windows 7 might block the z/TPF debugger, which prevents the z/TPF debugger session from starting. The CUD00003E error message might be issued on your z/TPF system. This message indicates that the z/TPF debugger was unable to connect to the workstation because of a timeout. The timeout is occurring because the firewall is blocking the z/TPF debugger.
In addition to the z/TPF debugger, the Windows 7 firewall might block other applications, such as TPF Operations Server and the FTP client.
Do one of the following actions:
- Disable the Windows firewall on Windows 7. Complete the following steps:
- On the taskbar, click Start > Control Panel > System and Security > Windows Firewall
- In the Windows Firewall window, in the left panel under Control Panel Home, click Turn Windows Firewall on or off
- In the Customize Settings window, under Home or work (private) network location settings, click Turn off Windows Firewall (not recommended).
- Click OK.
- Customize the Windows 7 firewall to accept the ports that are used by the z/TPF debugger and the TPF Operations Server native test environment.
