I am looking for suggestions regarding copying data from a Televideo 816/40 (CP/M - I think "concurrent") to an NCR Tower (System V). The Televideo system has a 40MB hard disc, and is now supporting two terminals. I am unfamiliar with this machine or with CP/M, and there is no technical documentation available. The system has a floppy disc and tape drive as well as several connnectors which appear (to my untrained eye) to be serial ports. The data to be transfered is primarily ASCII (printable). We have run a test conversion wherein a local firm converted a floppy disc from the Televideo system to 360kb IBM-PC format which I then read on the Tower. Using this approach, it is going to be a really long and complicated project to move 20-30MB. How feasible is it to connect the two machines and copy the data that way? What will the physical hook-up look like on the Televideo end? What programs and/or system commands will be needed at the CP/M end? (Is there an equivalent to "cat file > /dev/tty01" ?) Thanks in advance for your help. -- \/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\ Dick Gill Gill & Piette / PSG (703)761-1110 ..uunet!gillxp!rg

I also worked with such a Televideo a few years ago, but I don't remember all the details. I do seem to remember that there was a port on the back of the box labeled MODEM. Maybe that might mean something. I don't know what format the tape drive was. Could be that there's some potential there, too. I'd be interested to hear just ow you solve the problem in the end. *=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=* * Gershon Kunin * Data Communications * * Gershon@Barilvm.Bitnet * Bar-Ilan University Computer Centre * *=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*

Try bringing zmodem under cp/m and connecting the telewidget up to the Tower via RS-232 on one of the 800A Terminals. If you can't do zmodem then there are some good Ymodem, and modem 7 programs which should also be workable on the TVI. If you are into a little hacking then you can write a prgram to write through the 422 port on the telvideo server at very (for a z80) high speed (approx 115,000bps).

As quoted from <119@gillxp> by rg@gillxp (Richard J. Gill): +--------------- | I am looking for suggestions regarding copying data from a Televideo | 816/40 (CP/M - I think "concurrent") to an NCR Tower (System V). +--------------- If it's Concurrent CP/M (or possibly CP/M-86), you should be able to set the serial port with SETUP.CMD and then copy a file with the command PIP LPT2:=filename.ext (The device name may be wrong, I haven't used it in awhile and my manuals aren't readily available.) On the System V side, you can catch data from the port most easily with "cu -l/dev/ttyXX dir | tee file", but you will probably have to edit the file afterward. A method which avoids editing is somewhat more complex: $ sleep 30000 < /dev/ttyXX & $ stty icanon -echo eof '^z' ... < /dev/ttyXX $ for file in {put list of filenames here}; do > cat -u - < /dev/ttyXX | tr -d '\015' > $file > done This makes sure the port retains its settings, since after the last close it returns to the probably-useless default. The setting of "eof" allows the Unix system to detect CP/M end of file automatically, assuming the last line of the data file is terminated with the usual CRLF. (If it's not, you will have to separate the files manually anyway.) ++Brandon -- Brandon S. Allbery, uunet!marque!ncoast!allbery DELPHI: ALLBERY For comp.sources.misc send mail to ncoast!sources-misc
