There is a version of Cosession Remote called Cosession Remote 32 but is NOT compatible with Windows XP. It was only meant for Windows NT. If it is installed on a Windows XP machine, the keyboard will no longer work. I had a fun time removing it from an computer running XP. I had to use system restore to roll back the computer to a restore point before Remote 32 was installed. It had also disabled the Quick Login feature of XP.
There is also a version of Cosession Remote called Cosession 2000 but it is not compatible with older versions of Host.
Basically Cosession Remote is dead or what I like to call "Abandoned-ware" because it is no longer available or supported by the company that now owns it.
Here is a brief list of companies that have owned Cosessions Remote.
Triton Technologies. I've only seen this name on the original DOS version of the program.
Artisoft. I think they were the company who changed it to work in Windows.
Sparta Com. I don't know much about that company. If you try to go to their Website, www.spartacom.com
you will be redirected to Converging Technologies, where it says "Sparta Com is now Converging Technologies.
Converging Technologies. This is the current owner of Cosession Remote but they do not offer it for sale or have any specifications listed for it on their website.They do have some old technical support bulletins for cosessions but you have to do a search on the website to find them.
