I would consider it rather strange if setserial scrambles your modem's
eproms. setserial with SPD_HI simply records in the kernel, that next time
you try 38400, it uses 57600 instead (the same with SPD_VHI).
The other parameters to setserial, irq and baseaddress, shouldn't also
scramble you eproms.
(How about asking inconsisten questions to your computer, does it burn
it's boot proms? ;-)
