DOCUMENT:Q90473 07-OCT-1999 [win3x] TITLE :Which Redirector Works with Comm Server in WFWG PRODUCT :Microsoft Windows 3.x Retail Product PROD/VER:WINDOWS:3.1; :1.0 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows for Workgroups version 3.1 - Microsoft Workgroup Connections, version 1.0 ------------------------------------------------------------------------------- SUMMARY ======= Microsoft Comm Server is a LAN Manager server-based product that allows connectivity (over Token Ring) to mainframes from workstations running the Comm Server client software. The server portion of Comm Server, which resides on the LAN Manager server, transmits Comm Server client mainframe sessions (usually 3270 emulation sessions) using named pipes. The majority of these named pipes are asynchronous. This article discusses the use of Comm Server with Windows for Workgroups and Workgroup Connections redirectors. MORE INFORMATION ================ Comm Server requires the ability of the redirector to support asynchronous named pipes. The only redirectors that currently support this are the Vredir and the Full redirector. The Vredir is the preferred redirector to use with Comm Server because it can handle the multiple asynchronous named pipe requests that Comm server requires and it frees up more resources than does the Full redirector. The Full redirector does not have enough internal support to satisfy all the asynchronous requests of the Comm Server. Although the Full redirector does support asynchronous pipes, it cannot accept multiple requests at once. NOTE: The Full redirector does not support asynchronous named pipes inside of Windows, but it does support named pipes inside of Windows. The Basic redirector does not have named pipe support, and therefore does not work with Comm Server.
