Just a few random checks that come to mind:
* what is the chip controlling the serial port to the ISDN modem? Is it
an 8250 or a 16650? I seem to remember that the 8250 were not very good
but I don't remember when they stopped using them.
* check the serial port configuration. What is its baud rate?
* what is the CPU usage? To see if it's really CPU bound? Do the
system/user values look odd?
