To determine the size of the input buffer of the serial interface you are using, send SYST:COMM:SER[n]:PACE:THR:START? MAX. The returned value will be the buffer size less one.

… STARt must be set to less than … STOP.

The … THR:STAR command has no effect unless

PACE:PROT XON, … CONT:DTR IBF, or … CONT:DTR IBF has been sent.

Related Commands: … PACE:PROT XON NONE, … CONT:DTR,

CONT:RTS

*RST Condition: No change

Example Set interface to send XON when input buffer contains 10 characters.

SYST:COMM:SER0:PACE:PROT XON

SYST:COMM:SER0:PACE:THR:STAR 10

Comments

SYSTem:COMMunicate:SERial[n][:RECeive]:PACE:THReshold:STARt? [MIN MAX] returns:

The current start threshold if no parameter is sent.

The maximum allowable setting if MAX is sent.

The minimum allowable setting if MIN is sent.

To determine the size of the input buffer of the serial interface you are using, send SYST:COMM:SER[n]:PACE:THR:START? MAX. The returned value will be the buffer size.
