I now have FORTRAN IV actually working now. I did previously make FORTRAN IV "HELLO, WORLD" run, using the TYPE command, since I had troubles with FORMAT, but it turns out the troubles successfully using FORMAT and WRITE were actually problems with the math library functions. I rebuilt the fortran library with the hardware mult/div and it all works. So I found an RDOS KERMIT program source. It's actually the output of some RATFOR, for FORTRAN 5, but hopefully I can get it to compile on FORTRAN 4. My problem is more contemporary. The kermit source text is on my "terminal" linux laptop. I'm using minicom. I need to do XFER/A $TTI KERMIT.FR on RDOS to input the text, but minicom blasts the text out too fast. I solved this problem in another world at another time by writing a "text upload" that dynamically watched for character echo and self-paced; is there anything like this around? I guess I could hack something up in Perl, to simply delay 25mS per character, or something; or extract the CPU card and set the console speed to 300, bu sheesh, the source is 68,798 characters, I have to debug fortran4 vs. fortran5 issues as it is, I don't want to chase down dropped single characters at the same time. Is there any linux tool to do this sort of console-bootstrap thing, or a way to coerce minicom? (Delay after newline is useless, tried that, even 999 mS.)
