I have an LC-40 with the OSP-5000 control. I have a RocketPort (just a board with a lot of COM ports) connected to the PC, which runs Windows 98. I am using NCNET lite to transfer the program.
I made up the special serial cable according to instructions I read online. Bit parameter 1 is set to 00011011 and parameter 12 is set to 00100010 (some suggested the left most bit of parameter 12 should be 1, but when I enter a 1 it always changes it back to 0).
The baud rate is set to 4800, even parity, 7 data bits, 2 stop bits.
I am able to send programs from the machine to the PC with no problem - it works every time. I do this by going to the PIP menu, pressing the PUNCH key, then the command I use is "PUNCH ABC, CN0:" and it works.
When I try to send files to the control from my PC, it gives an error about 50% of the time, and when it sends it correctly, the file is either blank after the file name, or it contains some error codes the NCNET program sends, or it will have the complete program, but every 10 or 12 lines there will be several characters or a whole line missing.
I have tried changing all the settings in the NCNET program. If I adjust the # of stop bits, I get parity errors on the control. I have tried changing the flow control from hardware, software, none, both in NCNET but it always seems to do the same thing.
If I try to change the baud rate in the control (and on the PC) from 4800 to 2400 or 9600, I can't even send from the control to the PC - the file is all just garbled... but at 4800 baud it works every time, never a problem.
But I can't seem to send any files from PC to OSP5000.
I type "READ CN0:" and hit enter
If I don't get an error, then it will create a file called A.MIN, but when I look at this file, it will either just be the filename ($FILENAME.MIN%) and then blank after, or it will be the program, but have characters missing in various points or even a whole line or two missing.
Any clues?
Driving me nuts!
Thanks
