SYSTem:COMMunicate:SERial[ n] [ :RECeive] :PACE:THReshold:STARt

<char_count> configures the input buffer level at which the specified interface may send the XON character (ASCII 1116), assert the DTR line, and/or assert the RTS line.

Parameter	Parameter	Range of	Default
Name	Type	Values	Units
char_count	numeric	1 through 99 for built-in	none
		1 through 8191 for E1324A

•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.

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.
