As I read it, an sio2k.cfg file can only specify an address, not an IRQ. Somewhere
in the SIO2k docs I read something to the effect that it should never be necessary to
specify an IRQ, and no means are provided as it is automatic. I had tried to specify
the IO address using the syntax suggested in install.txt, LegacyIsa(IO1,IO2, etc), but
this didn't work. If I remember correctly, the modem would initialize and dial, but
hung the system when disconnection. I know, the modem isn't an isa card, but this
seemed to be the syntax for specifying an IO. I started preparing an SIO2k.cfg file,
but when I saw that there was no way to specify an IRQ, I abandoned that and tried
standard com.sys. Since it worked, and since the author strongly discourages using
SIO2k.cfg, I stopped there. If you think I should experiment further to investigate
a possible bug, I will.
