Or perhaps even easier (but perhaps not quite as efficient), create a 32-bit
WinSock/telnet version. This could be Synchronet-specific (getting the socket
handle from XTRN.DAT) or better yet, DOOR32.SYS compatible (which is supported
by Synchronet, Mystic and EleBBS at the moment). This would still be a
single-instance per user, but the fact that it was 32-bit and used sockets
directly would improve the performance dramatically.

Only slightly slower than a native 32-bit application.

Yes.

I believe (I don't have the docs in front of me), it only supports binary mode.

I believe it's _node_num (check DOCS\BAJA.DOC).

That is the account/user number.

Yes, unless the OFFLINE Baja function has been called.

You can use the OFFLINE Baja function and check for disconnection manually I
think (_sys_status bit ON_REMOTE).
