[Simh] Announcing TCP/IP for RSX-11M-PLUS

[Johnny Billquist]

Time for a new release announcement of TCP/IP for RSX-11M-PLUS.

Highlights:

- One bugfix in TCP, along with some new parameters to increase
flexibility and potentially performance.
- HTTPD can serve multiple hosts with different content from one machine
by use of virtual hosts.
- Lots of added functionality and features in MAIL.


Detailed information on things that have been done since the last release:


TCP:
- Bugfix in TCP. In a special case, a write on a socket could hang
forever on a closed socket.
- Improve TCP to not set PUSH on packets when we send FIN. Some hosts
and firewalls can dislike if PUSH and FIN are both set on packets, and
since FIN already implies that the stream is ending and whatever has
been received should be passed on to application at the receiving end
anyway, a PUSH is not really needed in that situation.
- Improved TCP RTT calculation.

IFCONFIG:
- Added SET TCP MINIMUM TRANSMIT TIMEOUT and TCP TIMEOUT WAIT commands.

FTP/FTPD:
- Added zeroing out partial last block when ftp in block or RSX mode.

HTTPD:
- Added virtual host capabilities to HTTPD.

MAIL:
- Added FLAG/UNFLAG command
- Added PREVIOUS command
- Added /HEADER switch to read
- Improved MAILD when running under virtual terminal (improved
interaction with PHONE)
- Added figuring out which user MAIL is running as when no accounting
exists for terminal
- Added handling of CC recipients in MAIL.
- Improved documentation.
- Improved notification processing.
- Added OS version information to MAIL.
- Added detection of DECMAIL11/RSX, DECUSMAIL/RSX and DECMAIL11/RSTS

RMD:
- Added exit ast handler to RMD.

SPOOF:
- Improve spoof notification handling.
- Changed spoof notification methods.



As usual, the distribution is available from:
ftp://mim.update.uu.se/bqtcp.dsk
ftp://mim.update.uu.se/bqtcp.tap
ftp://ftp.update.uu.se/pub/pdp11/rsx/tcpip/tcpip.dsk

The documentation is also available through ftp on Mim, or also at
http://mim.update.uu.se/tcpipdoc

I hope people find this update useful. While there are no really
critical issues that have been solved, I still recommend people to
update, since this new version do contain improvements that are
beneficial and as far as I know there are no issues or problems updating
to this newest version.
