Comments • While …PROT is XON, the serial interface will send XOFF when the
buffer reaches the …STOP threshold, and XON when the buffer reaches
the …STARt threshold.
• For an Agilent E1324A, AUTO is always ON. In this case
…[:RECeive]:PACE will also set …TRAN:PACE
• The XON character is control Q (ASCII 17
10
, 11
16
), The XOFF
character is control S (ASCII 19
10
, 13
16
).
• DIAG:BOOT:COLD will set …PACE to XON.
