Help: Zymate II Robot

I have purchased a Zymate II robot without its controller. There is an RS-232 style connector and a place for power and fuse. It is a cylindrical
coordinate robot and am happy to own it.
1 - What is the interface? Is it really a standard RS-232, serial interface that I can use with my PC?
2 - What is the command set that the controller will resopnd to?
Thank you in advance. John
PS - It would be nice if you respond to me personally, but I will be checking the newsgroup next week. Thank you again.
