Hi professor,

      Sorry to bother you, yet I got a problem about interrupt handler while doing LP driver. The problem is after int handler send data to printer once, it stops working. Could you take a look at my code under /home/wwgong/proj/lpsupport/xinu/lp.c and give me some hints? Thank you very much!


Best!
Weiwei

You need to send EOI to the PIC in the int handler!
See testlp.c's int handler.

Also practice final solutions.

I'll be in my office around 5:30pm with the projects. I'll
leave them in my dept. mailbox after that.
