Hi all,

i'm trying to write 7 bytes to an ethernet device.

When I write the bytes \x00\x13\x00\x00\x00\x00\x13 through the asynOctet I get what I expect:

2019/08/23 13:04:57.979 10.0.0.173:30305 UDP* write 7

00 13 00 00 00 00 13

When I try to do the same thing through stream device the output is not what I expect:

cmd:

drvAsynIPPortConfigure("OC_CMD", "10.0.0.173:30305 UDP*", 0, 0, 0)

Db:

record(ao, "$(P)$(Q):STOP") {
field(DESC, "Stop program")
field(DTYP, "stream")
field(OUT, "@OXCS700.proto stop($(P)$(Q)) $(PORTCMD)")
field(SDIS, "$(P)$(Q):DISABLE")
}

Proto:

stop { out "\x00\x13\x00\x00\x00\x00\x13"; }

Output:

2019/08/23 13:10:37.774 10.0.0.173:30305 UDP* write 2

02 13

Any idea what i'm doing wrong?

Thanks,
David
