Many of the TCP/IP companies have disappeared/consolidated into Micro Focus too, even the
ones who moved up the stack toward network clients and servers. Pretty impressive for a
company who used to be known for PC-hosted COBOL compilers.
Micro Focus acquired Attachmate WRQ who comprised Attachmate who had previously acquired
The Wollongong Group (TCP/IP stacks and applications for MS-DOS/Windows PCs, among other
things) and WRQ who had been in the terminal emulation business since the 1980s (first
product PC2622 emulated an HP 2622 terminal). Micro Focus also had previously acquired
NetManage (TCP/IP stacks and applications for Windows PCs) who had previously acquired
Wall Data (5250 emulator, maybe 3270 too) and FTP Software (TCP/IP stacks and applications
for MS-DOS/Windows PCs). I?m thinking Novell who acquired Excelan (TCP/IP coprocessor
hardware/software) is also somewhere in there via Attachmate WRQ.
I mean, really, who?s left? Distinct? (Though they seemed aimed more at protocol
libraries licensable to developers, now they seem to be in the TN3270/TN5250/VT420 for
Windows business.) Beame & Whiteside got et by Hummingbird who I guess are now
somewhere in OpenText.

I find it interesting that the field of comms interoperability with IBM mainframes was
huge up until TCP/IP
took over, and all traces of the software implementations have disappeared or were
consolidated into a couple
like Micro Focus. I have some old boards and documentation for
Unibus cards that would talk X.25, BISYNC and I think SNA. Any value?
yes, it would be good to get this archived on bitsavers
should talk to ethan about his stuff as well
