Have just upgraded home computer and now have Win XP Had to upgrade pcAnywhere from vers. 9 to 10.5. One PC that we have to communicate with for remote greenhouse environment control only runs DOS. PCAW 10.5 posts error message when trying to communicate with pcAnwhere 5.0 for DOS. On 10.5 CD says install from previous version CD (which was vers. 5.0 on vers 9 CD already installed on remote PC) Have been told not possible for PCAW 10.5 to access a DOS machine. Is this correct? Have thought about installing Win98 + PCAW 9 and running control program in DOS window but may not not work! Any proven solutions please would be gratefully received.
