Is anyone aware of a .NET API (commericial or free/open) that supports sending/receiving UPB commands with the UMC-DB9-W Serial UPB PIM? All that I've been able to find so far is UPB4Java (http://www.xpl4java.org/UPB4Java/UPB4Java/docs/ProgrammingWithUPB4Java.txt), which looks good but I'm not sure how stable it is and I'm really looking for .NET solution. Thanks.
