I am trying to access a door control access system made by siemens around the year 2009-2010, Sipass Entro, ver.6.5,
to use the data on a attendance program.
I installed that interface tcpip server, BAPSI,
(Bewatore All Purpose Socket Interface).
I work in VFP.
I tried to use this BAPSI in two ways:

1. Through BAPSIACTIVEXDLLNET.ocx -> it lets me create the object, but when I want to login, vfp OLE gives me the error: catastrophic failure.
2. I tried to implement Bapsi full, to directly control the bapsi server by tcpip through the windows winsock, it lets me do .conect() to the server, but when I try to send it the Login Packet Data, the server does not return anything , I’m probably not forming the string in .senddate() correctly.
   I tried to contact Siemens but they say that they no longer provide support for this product.
   In the Bapsi documentation from Siemens, I don’t have any concrete example of how to form that string of Data Packets.
   If someone has worked with something like this, even in another language, it could help me a lot, to see an example of how the string of DataPackets should look for Login to the Bapsi server.
