I connect to the Internet using a wired DSL router. I do not know how to connect via the command prompt... I know you said to connect using a client and not a web browser, but out of curiosity I tried using Internet Explorer 9, which triggered a Windows Firewall notification! Open a command prompt (cmd). Using the username of 'Anonymous' and the password of your email address, you can attempt to connect. Here is my example I just did. C:\windows\system32>ftp usftp.clevo.com.tw Connected to usftp.clevo.com.tw. 220 Serv-U FTP Server v7.3 ready... User (usftp.clevo.com.tw:(none)): Anonymous 331 User name okay, please send complete E-mail address as password. Password: 230 User logged in, proceed. ftp> Of course, it won't show you what you are typing at the password prompt, so hope to not make a typo! You shouldn't even get to the prompt for the username if the port is blocked tho.
