It seems logically like there would be, but I can't find much information.
I found an IBM AS/400 manual from 1997, OS/400 Internetwork Packet Exchange (IPX) Support V4R1, which briefly mentions using TELNET with IPX (page numbered 68, PDF page 80):
The jobs that are started by the Start IPX (STRIPX) command are the following:
|QIPX||Main IPX job|
|QAPPCIPX||APPC over IPX applications|
|QTVIPXTELN||TELNET over IPX job|
|QTVDEVMGR||TELNET Device Manager job|
A September 1997 IBM Software Announcement for IBM eNetwork Personal Communications Version 4.2 describes this feature:
TN5250 over IPX/SPX Socket: For 5250 emulation, provides support for Personal Communications as the client side of the connection using the transport protocol AF_IPX over an IPX/SPX socket
TN5250 is just a profile of TELNET, defined in RFC4777 (and its predecessors). Unlike TN3270, it does not use a custom TELNET option (29 for classic TN3270 and 49 for TN3270E), it is negotiated by a specific combination of standard TELNET options. So TN5250 over IPX requires plain TELNET over IPX as a prerequisite. But it isn't clear how TELNET was actually carried over IPX/SPX. Although a "Netware IPX Socket List" reports port
0x9072 as allocated for "SPX TELNET" by "UNIVEL" (Novell and AT&T's Unix subsidiary).
Some other IPX/SPX-based protocols I'm aware of, which while not TELNET perform a comparable function:
- Novell's NACS (NetWare Asynchronous Communication Service) and NASI (NetWare Asynchronous Services Interface) – which may be two different names for the same thing. MS-DOS Kermit supported them. Ralf Brown's Interrupt List reports it as using INT 6B, and also mentions that Ungermann-Bass Net One was another product with the same API.
- MS-Kermit also supports something else called "Novell TELAPI", which the Interrupt List also refers to. It also calls it "Novell LWP TELAPI", suggesting it may have something to do with Novell's "LAN Workplace Pro" product
- I suppose Netware RCONSOLE is another thing which was conceptually similar. I found a buggy / probably non-functional implementation of an RCONSOLE server for FreeBSD. That code reports it uses SPX port
0x8104, which also agrees with the "Netware IPX Socket List" I quoted above.
Can anyone add anything to the above?
