An attempt to access the floppy drive during dosemu produces the
following:

gettimeofday({922292676, 183447}, NULL) = 0
read(3, 0x80d42e5, 128) = -1 EAGAIN (Try again)
ioctl(3, TIOCMGET, [TIOCM_DTR|TIOCM_RTS|0x4000]) = 0
read(4, 0x80d4564, 125) = -1 EAGAIN (Try again)
ioctl(4, TIOCMGET, [TIOCM_DTR|TIOCM_RTS|0x4000]) = 0
read(5, 0x80d47dd, 128) = -1 EIO (I/O error)
ioctl(5, TIOCMGET, [TIOCM_DTR|TIOCM_RTS|0x4000]) = -1 EIO (I/O error)
read(6, 0x80d4a59, 128) = -1 EIO (I/O error)
ioctl(6, TIOCMGET, [TIOCM_DTR|TIOCM_RTS|0x4000]) = -1 EIO (I/O error)
vm86(0x80aef9c) = -1 ENOSYS (Function not implemented)
