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

[Mark Matlock]

Johnny,
   Thanks again for the updates to BQTCP/IP !!!

    It has been running great on my PDP-11/83 and for a bit now I've been picking up your RL02 disk images directly from the 11/83 with this batch job:

$JOB /TIME=(1:00) FTPXFR
$SET /UIC=[6,1]
$SET /DEF=DU1:[MATLOCK]
$FTP
open ftp.update.uu.se
anonymous
anonymous
cd pub
dir
cd pdp11
dir
cd rsx
dir
cd tcpip
dir
status
rstatus
mode block
progress
get bqtcp.dsk
close
quit
$vcp con bqtcp.dsk/DRV:DU
$vcp show all
$mou du2:/ovr/pub/vi
$EOJ

    My system startup file asks whether to bring up BQTCP/IP and after I download the new version, I reboot not loading  BQTCP/IP and then have a command file that copies the updated files from the BQTCPIP.DSK to LB: and I run a fresh IPGEN This has made the updates pretty quick to apply from your updates that have been coming over the summer.

  The telnet client has made it very convenient to open multiple terminal windows on my iMac using PowerTerm to telnet to the 11/83. It has made RSX programming and debugging much more fun.

Thanks and keep up the great work,
Mark

For anyone who is currently running TCP/IP for RSX, I strongly encourage you to update to this latest version. Several improvements have gone in in the last couple of weeks. Most important change is that there now is telnet support, both client and server side.

The API is not compatible, even at the source level, with Unix, but on the other hand, if people write some code, they will see that it is a very easy API to work with. The reasons for the incompatibilities are several, including both resource concerns and differences between how RSX works and Unix like operating systems.

It do require RSX-11M-PLUS with split I/D space, and it has only been tested properly on RSX-11M-PLUS V4.6. It should work on any version 4 release of RSX-11M-PLUS, but there might be a couple of tweaks or fixes needed.

The actual TCP/IP stack sources are not included. I do not have a good setup for distributing them in a sane way, and it has had a low priority on my list of things to do. But I do not mind distributing the sources as a general principle.

BQTCP/IP is already running on the internet, and have been for a while. People who are curious to check it out can ether look at http://madame.update.uu.se/, or telnet to telnet://madame.update.uu.se and login as user GUEST with password GUEST, or use ftp against ftp://madame.update.uu.se. Anonymous ftp account exist.
