User Module Description
The user module “SerialStats” allows you to easily and visually inspect advanced serial port statistics. It is based on the “TCIOCGICOUNT” Linux kernel ioctl. It displays the interrupts the Expansion Port 1 and Expansion Port 2 receives during operation.
Note: Both 1 to 0 and 0 to 1 transitions are counted, except for RI, where only 0 to 1 transitions are counted.
Value | Description |
CTS | Interrupts on Clear to Send line |
DSR | Interrupts on Data Set Ready line |
RNG | Interrupts on the Ring Indicator line |
DCD | Interrupts on the Data Carrier Detect line |
This module only displays meaningful statistics as long as another application accesses the Expansion Ports. If they are not being used the statistics will reset to zero.
