tannerd Posted February 24, 2011 Posted February 24, 2011 Is it possible to manually control the states of the RTS and DTR lines on a serial port? Likewise, is it possible to see the states of the CTS, DSR, DCD and RI lines on a serial port? If so, how?
AzeoTech Posted February 24, 2011 Posted February 24, 2011 No. The only way you could do it would be to write your own C++ DLL and link it in using DAQFactory's extern() function. But then you wouldn't be able to access that serial port from within DAQFactory.
