chet@Advansoft.COM (Chet Wood) asks about connecting his Mac with an
Apollo Domain/OS unix system, without using kermit. I've prepared the
following, for our internal use.
How to connect a Mac to an Apollo
The fastest way to connect a Mac to an Apollo is to buy an Ethernet
Card, for either a Mac II or SE/30, and connect into the network using
NCSA Telnet or some other TCP/IP software. The research I did showed
that the Racal-Interlan cards delivered the most for the best price.
For people willing live with a transfer rate of about 1.5K cps, do the
following:
Hardware
1. Get (or make) a null modem Mac-to-RS232 cable.
2. Connect the modem port in the back of the Mac (the one with
the phone symbol) with the tty01 port of your DNXXXX.
3. Edit the file /sys/node_data/etc/ttys , and change the line
tty01 none dumb off secure
to
tty01 "/etc/getty 19200-baud" vt100 on secure
4. (As root), send a HUP signal to the init process, by
# kill -1 1
5. Check and make sure the process is running:
# ps ax | grep tty01
7392 ? S 0:00 - 19200-baud tty01
Software:
1. Find a Mac terminal emulator that supports the zterm protocol.
ZTerm is $35 shareware, available from sumex.stanford.edu as
file /info-mac/comm/zterm-085.hqx . Various commercially
available programs support zmodem, as well. Send in your
shareware fee if you use zterm regularly.
2. Get the Unix zmodem package, and compile it. It is available
from sumex.stanford.edu as /info-mac/unix/zmodem-part[1234].shar.
This will give you the rz and sz programs.
Mac Usage:
You're on your own, as far as getting the zterm-085.hqx file turned
into an application on your Mac. Once you get it unbinhexed and
unstuffed, double click on the ZTerm icon. Set the baud rate to
19.2K. The other default settings are harmless. You should now see a
login prompt, although it may be garbled because of a problem with
getty and 8 bit output. Just type in your login normally, and things
will get back to normal.
Modem usage:
If you are dialing in over a phone line, then use a modem Mac-to-RS232
cable. Set your baud rate to whatever your telecommunications
equipment expects. Follow your usual dialup proceedures to log in.
File Transfers:
To send files from Mac to Apollo (upload):
Type "rz". It will type back
rz ready. To begin transfer, type "sz file ..." to your modem program
and start sending out magic zmodem characters. Use the pulldown menu
to start a zmodem upload.
To send files from Apollo to Mac (download):
Type "sz file1 file2 file3 ... ". It will respond
Sending in Batch Mode
and wait. The Zterm program will catch the magic zmodem characters,
and put the requested files onto your Mac disk.
There may be occasional problems with the interaction between sz and
your network. If you are getting a throughput of 3%, rather than
75-90%, try copying the sz program, and the files you want to download,
onto the /tmp directory of the node you are logged into, and executing
the binary from there.
Another incredibly useful Unix program is mcvert. Mcvert converts
binhexed *.hqx files into MacBinary *.bin files. ZTerm will take the
MacBinary file and directly put it on your Mac - you don't need to run
binhex on your mac! mcvert is available from sumex.stanford.edu as
file /info-mac/unix/mcvert-15.shar .

I regularly do this and find that sending from the Apollo to the Mac usually works okay (although it works more reliably if I use the -e flag to escape control characters). To the Apollo almost always fails at 19.2 and often fails at 9600. The transfer just locks up, particularly if anything else is happening on the Apollo at the same time. I suppose it's too much to ask that someone finish tty support in SR11? (The person working on it at SR10 left Apollo in the middle and as far as I know nothing has been done since.) -kee -- Alphalpha Software, Inc. | motif-request@alphalpha.com nazgul@alphalpha.com |----------------------------------- 617/646-7703 (voice/fax) | Proline BBS: 617/641-3722 I'm not sure which upsets me more; that people are so unwilling to accept responsibility for their own actions, or that they are so eager to regulate everyone else's.
