Pyvisa timeout on read

A character was not read from the hardware before the next character arrived. As far as I know, pyVisa is reading too slow when compare to speed of data sending. Same procedure is working when I am using pyVisa/GPIB, or pySerial/COM. How can I make it faster, or what can I do to get that data by pyVisa/COM?Oct 14, 2020 · PyVISA started as a wrapper for the NI-VISA library and therefore you need to install the National Instruments VISA library in your system.
