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 1710, 1116), The XOFF character is control S (ASCII 1910, 1316).

DIAG:BOOT:COLD will set … PACE to XON.

Related Commands: … PROTocol:THReshold:STARt,

PROTocol:THReshold:STOP, … TRAN:AUTO

*RST Condition: No change

Example Enabling XON/XOFF handshaking.
