Hi Priya,

A quick way to do this would be to attach an asyn record to the serial port, and use a sseq record to control and send strings to it.

record(sseq, "doReset") {

field(STR1, "Read")

field(LNK1, "asynrecord.TMOD")

field(STR2, "*RST")

field(LNK2, "asynrecord.AOUT CA")

field(WAIT2, "Wait")

field(STR3, ":SOUR:FUNC VOLT")

field(LNK3, "asynrecord.AOUT CA")

field(WAIT3, "Wait")

...

field(STR7, ":OUTP ON")

field(LNK7, "asynrecord.AOUT CA")

field(WAIT7, "Wait")

field(STR8, "Write/Read")

field(LNK8, "asynrecord.TMOD")

field(STR9, ":READ?")

field(LNK9, "asynrecord.AOUT CA")

field(WAIT9, "Wait")

}
