Trying to use the Host "Confirm Connection" prompt to secure a POS system for PCI compliance.  However, there are times that the POS vendor wants to schedule after hours database maintenance, etc.  I'm thinking the POS system could be programmed to execute a file with an on-line parameter or something whenever a specially encrypted e-mail message is sent to it.  Is there a hook into pcAnywhere to "answer" the "Confirm Connection" dialog programatically?  I don't think I'd want to override pcAnywhere to temporarily not prompt to confirm as then any user could in theory get in for that time window. 

I'm thinking this might be more straight forward than setting up an RSA SecurID server or SSL certificates to get two factor authentication.
