I want to connect a TCP/IP workstation and 5250-based applications on an AS/400. 5250 is the default or native data stream supported on the IBM AS/400 and the IBM S/3x (as opposed to the 3270 data stream used for MVS and VM systems). The workstation is on Ethernet and runs HP-UX, which is compatible with UNIX System 5.2 and BSD 4.2. The AS/400 is on a Token Ring and I know how to bridge the Token Ring to the Ethernet. Based on what I've learned so far, one of the following might work if I can find the necessary components: 1) "TN 5250" extensions to Telnet. I know that RFC 1041 defines a Telnet 3270 Regime Option which supports the 3270 data stream within the Telnet protocol. I've not been able to find a similar regime option for the 5250 protocol stream. I also understand that IBM does not presently include Telnet as part of its TCP/IP support on the AS/400, but that they have made a Statement of Direction for it. 2) An X-Windows 5250 emulation package for the workstation which can talk directly to the AS/400 or go through an intermediary system. I'd prefer a full-blown X application, but I'd consider a character-based application accessed by something like xterm. 3) Support of APPC/LU6.2 on HP-UX over the workstation's Ethernet interface. Ideally this would include support for the 5250 data stream under LU6.2, but I'd be happy just to find a vendor that provides the LU6.2 support. Any pointers or suggestions would be greatly appreciated. I don't regularly subscribe to this newsgroup, so I'd appreciate your replying directly to me via email at the address given below.
