Tspnet.readavailable() - Keithley 708B Reference Manual

Models 707B and 708B Switching Matrix Reference Manual
Details
This command reads available data from the device and returns the number of arguments.
The format string can contain the following identifiers:
%[width]s
%[max width]t
%[max width]n
%d
If formatString is not provided, the command returns a string containing the data until a new line is reached. If
no data is available, the Model 707B or 708B holds off operation until the requested data is available or until a
timeout error is generated. Use tspnet.timeout to specify the timeout period.
When reading from a TSP-enabled remote device, the Model 707B or 708B removes TSP prompts and places
any errors received from the remote device into its own error queue. The Model 707B or 708B prefaces errors
from the remote device with "Remote Error," and follows this with the error number and error description.
Example
tspnet.write(myID, "*idn?\r\n")
print("write/read returns:", tspnet.read(myID))
