Simple shell in VB.Net

Today I've imported an old project from VB6 to VB.Net. It's a 'shell' with TCP connection module integrated (like 'telnet'). There are integrated basic commands like 'dir' or 'ls', 'rm', 'rmdir', etc. You can connect to TCP server with command 'connect IP PORT'.
You can download binaries or sources (VB.Net 2008 Express):
