Thanks for the forward Les, but it appears that my post did make it to the list - about an hour after I sent it. Not sure if that is the way everyone's emails are posted or if "someone" down the pipe had to approve my post before it got sent to the list.

It was written by Christian Kulovits (Austria). Its stated purpose: "RxComm is a REXX Communications application programming interface (API) package that provides access to serial communications devices from your REXX program." The web site also says "Version 1.3 with support for multiple REXX interpreters. (Regina, Raginald [sic], Object Rexx, Enterprise Rexx and Personal Rexx)" http://members.aon.at/kulovits/christian/downloads.htm I have no idea if it works, but at least this will maybe bring the conversation back on topic.
