Releases prior to 3.3:
Spurious interrupt means that CTS and/or DCD startled toggling (low to
high over and over) more than 10,000 times in a one second window.
Either one or both of those signals toggling like this will cause a
Spurious Interrupt.
Release 3.3 and up:
Serial port spurious interrupt handling has been extended to include
detecting streams of framing errors. Some modems get confused about
their configuration and begin sending continuous data to the
PortMaster at a baud rate different than set on the PortMaster. This
would cause all operation on the PortMaster to appear stopped for
several minutes to several hours. The PortMaster now attempts to
reset the modem and will continue to operate properly even if the
modem does not recover.
