I wrote a graphics package in C and tested it out by writing a simple polyspi (squiral) drawing algorithm. It went through the first few iterations nicely, but then the screen just scambled in went into snowy mode. Thinking that was weird, I took my disk to a local IBM User's group meeting that night. The only computer to run it on was a Compaq, so I did and the program worked perfectly. Thinking the problem was in my machine, I tried the program out later on a friends machine, and it mutiliated the screen just like it did to mine. Common sense tells me that if it works on a Compaq, it should have worked on the PC, leading me to believe that there is a bug in the PC hardware or firmware itself (I'm using BIOS call 0x10 for Video I/O) Anyone have any suggestions? Also, I was considering purchasing a US Robotics Password modem. Has anyone used one and have info on how well it's made and how Hayes compatible it is? Thanks in advance. _____________________________________________________________ Jordan Bortz UUCP : ..decvax!cbosgd!mddc!jordan ARPA : ..cbosgd!mddc!jordan@berkeley.ARPA FLAMES : /dev/null on your local system
