  When you're remotely logged into P9 box using telnet protocol,
  you can use 0x7f key ( BackSpace/Del key on some UNIX'es ) to kill a process.

  From sys/src/cmd/ip/telnetd.c:

/*
 *  Read from the network up to a '\n' or some other break.
 *
 *  If in binary mode, buffer characters but don't
 *
 *  The following characters are special:
 *      '\r\n's and '\r's get turned into '\n's.
 *      ^H erases the last character buffered.
 *      ^U kills the whole line buffered.
 *      ^W erases the last word
 *      ^D causes a 0-lenght line to be returned.
 *      Intr causes an "interrupt" note to be sent to the children.
 */


Thanks,
Roman.
