No telnet commands work after success telnet connection
Please help!!
After telnet to an VxWorks system, the command line shows the name of the server correctly, but no telnet command works, like "ls, dir, delete, rm..........", the error message is always "undefined symbol". This telnet worked early this afternoon, I forgot what I did to mess up the whole thing. I did not touch any hardware, and I did not edit the VxWorks system files, the only thing I did was telnet and ftp to it.
Please help me!!
