RXASYNC: Difference between revisions

Revision as of 02:16, 3 January 2021

RXASYNC.DLL is a REXX DLL which provides full exposure of the OS/2 Asynchronous communications API and thus enables REXX users to fully exploit the scripting advantages of REXX and OS/2 serial communications. Works with SIO and standard COM drivers. The source for IBM Developer's Workframe/2 is included.
