Abstract:

The 'TCP/IP Package for TSX-Plus' provides TCP/IP networking services
for multiple users with TSX-Plus.  The package is an assemblage of server
and client programs designed to provide Telnet, FTP, Mail, POP3, LPD, and
HTTP services for local and remote users of TSX-PLUS systems.  The
programs are written in C and RT-11 macro. A security system
allows usernames/passwords and authorizations for each client/server
component to be specified for each user.

The sources for the 'TCP/IP Package for TSX-Plus' include
header, command, C language, and macro files.  The DECUS C compiler
(with some bug fixes) and AS assembler are included with the software
distribution to allow the package to be recompiled from the supplied sources.

The current implementation uses 8 global regions to support
multiple client/server programs simultaneously.  The number of
regions used by each service is TELNET(1), RTELNT(1), FTP(2), FTPL(2),
RFTP(2), MAIL(1), RSMTP(1), RPOP3(1), MMAIL(1), MAILER(1), CNCT(1), RCNCT(1),
RHTTP(1), RGOPH(1), NTSND(1), LPQRM(1), and RLPD(1).

The hardware requirements are a TSX-PLUS system having a minimum of
512k bytes of memory, a DEQNA/DELQA (Q-Bus) or DEUNA/DELUA (Unibus)
ethernet card with associated thick or thin wire adapter, and optionally a
pair of dedicated serial lines for each simultaneously active
remote Telnet session.
