We are recommending MC9090 as the replacement of a customer's Teklogix / LXE mobile computers. Their question is whether we have the same SPARCS RDT Interface as our competitors have. If we have so, what version it is? If that version is not compatible with their current system, should they buy some licenses to resolve that issue? I heard that some port customers of Teklogix mobile computers use a propriety interface to connect their terminals to SPARCS host. It is a kind of telnet, but not the standard one. So, Wavelink does not support that? I also heard that Navis is developing a GUI client. Will it supports our MCD products? Thank you! Junhua
