I have been working off and on for some time to get Dave Dunfield's NST (Northstar disk image transfer) program working on a laptop which is communicating with my IMSAI via a serial cable. His procedure of "typing in" the I/O stub (hex file transfer) to the micro using the Northstar Monitor doesn't work for me because I don't have a typical CRT monitor connected to a serial port. On the other hand, I do have a working system with two operational N* disk drives, so I was able to type in, assemble and save the I/O stub configured for my serial port under N* DOS.
I have been using a Win98SE laptop which I booted to DOS to run the PC program which sends and receives files. It won't communicate when running under DOS, but works fine when I run it from the Command line prompt under windows. I ran Checkit (both ways) and it reports the COM1 port is fine. A couple of serial port configuration checkers I tried ran under windows, but not under DOS. I tried the DOS MODE command to set up the COM1 port, but that doesn't make any difference. I wasted a lot of time before trying the PC program under Windows 98SE.
Any idea why the COM port is not working under DOS? No big deal I guess, since I am now able to upload and write N* DOS images, CP/M images, and UCSD Pascal disk images. This leads me to ask another question. Does anyone have a scanned copy of the Fortran-80 user manual (CP/M)? I tried Bitsavers.ORG and H. Harte's website.
