[Elecraft] Windows 7 64bit and USB to RS232 adapter

[Dick Dievendorff]

I think I understand that issue. Sometimes the driver issues a data available signal but when you subsequently ask for the data, none is there.  My view is that this boundary condition could have been handled a bit better by the MS VB common communications DLL, but my view doesn't help the poor guy using That DLL. 

You make a good point, but I'm not sure Prolific is entirely at fault here.

These logging programs were complied using Visual Basic and I was told that the Prolific driver and Visual Basic had a register conflict.  When I bought the PCIe RS-232 card it cured my problems and I have not worried with it since.  I got the latest Prolific drivers from the web site a little over a year ago, but have not updated them since I quit using the Elecraft supplied Prolific converter.
