Hi Mark,
Use the prompt as a terminator.
InTerminator = "> ";
out "data?"; in "data?" CR "%{0|1}" CR;

I am trying to write a StreamDevice protocol file for a Thorlabs SC10
shutter Controller and have struck a problem.

The protocol to obtain eg. “data” is to send the string “data?”. The
device then responds in three steps:
* echoes the request string “data?” followed by a terminator (CR)
* provides the current value (0 or 1) followed by a terminator (CR)
* sends back a prompt string“> “ BUT WITH NO TERMINATOR

I can handle the first two steps:

TERMINATOR=CR
getData {
 out “data?”; in “data?”; in “{0|1}”;
}

How do I best handle parsing the trailing characters of the prompt
string “> “ which is not terminated?

I will be polling the device for multiple pieces of data.

Thanks in advance,
