Jay, Shmuel is right - he often is - well, half-right, but I'm not deducting any points for not mentioning VM. In other words the ICA is supported only under VM and VSE VTAM .
>From your post I used "AWSICA" as a Google search word and confirmed the above in one or two "hits". I vaguely remembered this also at the time I mentioned the ICA but, since the original poster didn't specify MVS-z/OS, I didn't bother to mention anything. One of the "hits" was http://www.hammocktree.org/tech/P390QRef.PDF entitled "IBM PC Server System/390 Quick Product Guide" where we find the following: "OS/390 (MVS): OS/390 does not support the ICA so AWSICA cannot be used and BSC line support is not provided. SDLC support for OS/390 is provided by the WAC (Wide Area Connector) and MultiPort Model 2 adapters by using the WAN3172 device manager, emulating a VTAM XCA node ("3172 SDLC Gateway"). The WAC can be configured for either RS232, V.35, or X.21 interfaces. (RS232 typically runs up to 19.2Kbps, V.35 is used for 56Kbps and higher, with X.21 being used for very high speed, such as T1 connections.) Each WAC has one line interface and one additional interface can be added (interface types can be mixed). There is a maximum of 2 WAC adapters per system since the PB0 only has two ISA slots. The MultiPort model 2 provides up to 8 RS-232 ports per adapter, with a maximum of two adapters. Only ISA bus versions of the WAC and MultiPort model 2 are supported. CHECK: IS WAN3172 plus Portmaster 2 supported on OS/390?" It may be something like this you recalled. Clearly there's some sort of "smoke and mirrors" here where VTAM thinks it's dealing with a LAN - although the interface is the "Link Services Architecture" (LSA) interface - while the adapter is driving SDLC. But this sub-issue got off the ground because we were talking about the 3767 and there's a snag - not that anyone really should care since we are all well away from the original topic. The snag is that, in addition to using LU type 1 protocols, the 3767 also uses PU type 1 protocols. PUTYPE=1 is not an option with the XCA major node PU statement.
