[net.micro.pc] Color Card BUG + modem info

jordan@mddc.UUCP (07/21/83)

I think I found a bug in IBM hardware and was wondering if anyone out there
knows the solution....

	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.
