Yes, CMS only licenses simultaneous "CV-SUP" connections. Regular telnet sessions are not limited. DSA, terranova, or procomm all work well just via telenet using 4410 or 615 terminal types. Most of the reports are there, it's just not a nice GUI and you will be unable to print as easy as with CV-SUP. Your printing will be limited to simple screenshots or via printers you have setup in the UNIX server itself.
