I am in a rather annoying situation of having one serial application
not work well with the uart driver (null modem cable connects onboard
serial ports to a machine I have no control over) and a GPRS device
where the sio driver causes a constant stream of interrupt overflows
sio4: 109 more interrupt-level buffer overflows (total 109)
sio4: 109 more interrupt-level buffer overflows (total 218)
sio4: 109 more interrupt-level buffer overflows (total 327)
sio4: 109 more interrupt-level buffer overflows (total 436)
sio4: 109 more interrupt-level buffer overflows (total 545)
sio4: 109 more interrupt-level buffer overflows (total 654)
sio4: 109 more interrupt-level buffer overflows (total 763)

cisvendor="Sierra Wireless" cisproduct="AC860" function_type=2
Attaching even at 9600 on this card, shows half of the chars are
missed. However, with the uart driver, it works. The one small
problem is that until I open the device, there is an interrupt storm
on it. But after that, it works perfectly.
e.g. attaching with sio shows the output of ati3 cut off
