Hey all, just wondering if anyone has any input on a program that gets stuck in a loop.

This is a C64 "Petscii" program for telnet on Amiga platforms. Sounds fun.

It pegs the CPU and can't be killed via shell and it never gets to GUI to use iKill either.

Any tips appreciated!

This is a log of the loop shown twice:

Front and foremost, it tries to read some legacy Amiga custom register 0xDFF006 VHPOSR according to the log, most likely to read some beam position where it is very unlikely to get the desired result when run directly with MorphOS ...

You definitely need to run this through some full emulator to have a chance of seeing it to do anything useful, albeit questionable.

It seems to be quite problematic even on real Amigas too:

well, yea, thx for the link, it seems to bang the legacy Amiga H/W all over the place, so not really something that fits into the MorphOS 68K compatible without additional h/w emulation layer category ...

Thanks for bearing with me as I learn.

I am a bit too green to know how to determine if programs require the chipset. I did have a bit of hardware trouble tripping me up for the last few months though...

After building this G5 11,2 for MOS I experienced a great deal of stall/hang/loop/crash. I've fixed monitor/gpu compatibility issues recently so I finally have legitimate mysteries to deal with. (DCTelnet Settlers2, UAE and others used to give me trouble but now work fine).

I see in the UAE compiling docs that bsdsocket is nix only so I don't get to tinker with 64Door on my MOS G5. Bummer !

Thanks for the insight guys,
