H.P., (huge pile)6357, win 98se., un-installed working ultra slow modem, installed creative sound blaster, and computer can't open the com port. Seems like modem used to use com2, but now only have com1 to pick from. I used, and followed all the trouble shooters to the end, bios shows com2,3,&4 as oo oo, com 1 does show actually as f8 03., but puter cannot find, & obviously not open, so...............?? Thanks in advance!!
