I have Minix 1.3 running now, but have an odd thing happening with clr.c. It takes about 10 seconds to clear the screen. I am using a termcap that was posted here a while back. Since I just got 1.3 running late last night I'm not totally familiar with the whole 1.3 system and how everything integrates, but I don't see what I'm missing. Any thoughts? P.S. I found reference to a lib/IBM_PC/prtso.s but it didn't come in the upgrade package from bugs and I didn't come across it in my 1.2 source. Could someone tell me where it's located in the source directories, or mail it to me. Thanks -jeff- -- Jeff Holmes DOMAIN: jeff@questar.mn.org Questar Data Systems UUCP: amdahl!bungia!questar!jeff

I would suggest doing: chmem +8000 clr to see what happens. The stdio package often tries to malloc memory and if that fails, does everything 1 character at a time. This makes things slow. I don't know if this is relevant here, but it is worth a try. When you figure out what is going on, please post a short note. This sort of problem is reported not infrequently.

I also moved the termcap entry that applies to my terminal in etc/termcap to the top of the file, sometimes it works faster if the termcap routines don't have to read through alot of irrelevent entries.
