When I connect some device to the com port,like an external modem, the keyboard don't work and the Num Lock indicator flash sometimes. As a result, the computer can't work. But It can function well if nothing connected to the com port. Are there some problem with the BIOS?
Thanks a lot.

Is it ATX or AT board? If it's AT then the COM port connector might be connected the wrong way to the header on the board (check pin 1 orientation)

Will it cause by some virus?
