  62 The keyboard abort sequence effect can only be changed by a super-user using
  63 the \fB-a\fR option. This sequence is typically Stop-A or L1-A and Shift-Pause
  64 on the keyboard on \fBSPARC\fR systems, F1-A and Shift-Pause on x86 systems,
  65 and BREAK on the serial console input device on most systems.

  68 A \fBBREAK\fR condition that originates from an erroneous electrical signal
  69 cannot be distinguished from one deliberately sent by remote \fBDCE\fR. As a
  70 remedy, use the \fB-a\fR option with Alternate Break to switch break
  71 interpretation. Due to the risk of incorrect sequence interpretation, binary
  72 protocols such as \fBSLIP\fR and others should not be run over the serial
  73 console port when Alternate Break sequence is in effect.

  76 Although PPP is a binary protocol, it has the ability to avoid using characters
  77 that interfere with serial operation. The default alternate break sequence is
  78 CTRL-m \fB~\fR CTRL-b, or \fB0D 7E 02\fR in hexidecimal. In PPP, this can be
  79 avoided by setting either \fB0x00000004\fR or \fB0x00002000\fR in the ACCM.
  80 This forces an escape for the CTRL-b or CTRL-m characters, respectively.
