Now, its taken awhile, but we're starting to get some place. If you'd mentioned that it was a 700 MHz machine in the first place, it might have helped. So, what kind of 700 machine is it? What do your config files look like? How busy is the machine when it gets these errors? What else can you tell us about the system? Because if this modem is supposed to just look like any other serial port to the system, then this would almost certainly be a global problem with all 56k modems if it was the serial driver, but since its obviously not, lets see what makes you different, shall we? If nothing makes you different, and if it does turn out to be a problem between sio and these modems, you'll need to file a pr so it can get fixed. To be honest though, I still suspect something in the config. It does appear to be a hardware modem from looking at Zoom's product description, so at least we aren't talking about a winmodem.
