This archive contains two files: SAXXFR10.DLL and SAXCOM.VBX. To install, copy them to the following directories: - The DEBUG directory under your Sax Comm Objects directory - The NODEBUG directory under your Sax Comm Objects directory - The Windows System Directory. The file transfer module, SAXXFR10.DLL fixes a problem that some people had with file transfer speed. The VBX contains has the InitModemForAnswer property, and fixes a problem with the FillModemList and FillModemCombo properties. It's important that the MODEM.LST file is in the same directory as your .VBX file, because that's where these properties look for when opening the modem database. Also, when using the code: SaxComm.FillModemList = ListBox.hWnd make sure that the listbox control is already created. For example, if you use this code in the Load event of the form that contains the listbox, you will get an "Access denied" error, because the listbox window isn't created at that time yet, so it doesn't have a valid window handle.
