I'm using php4 to connect to an old router.
Once the connection is made and I've logged in I send a series of commands..
As I know the output of the router I can answer the questions it is asking directly, so I send :
fputs($fp,"Upgrade"); // run upgrade command
fputs($fp,"y"); // Send y for Yes
fputs($fp,""); // send return
The next line I need to send is backspace 5 times. I've tried
fputs($fp,"\^h");
fputs($fp,"\x08");
fputs($fp,"\BS");
they all send but nothing is back spacing.. how do I send 5 backspaces to delete the current entry and then I can send my new entry ?
Thanks
Have you tried sending
chr(8)
directly (no String operations etc.)?
Do you know whether the router uses standard telnet protocol or is it a proprietary (extended) protocol used by some special router management application?
