That’s expected. The PI40952+3x2B driver package often includes:
128-byte hardware FIFO depth for deep buffering, mitigating data overrun packet drops.

The product code refers to a DeLOCK PCI Express Adapter Card that adds two serial RS-232 (9-pin) ports and often one parallel port to a computer. Driver Update Guide
The is a PCI Express (PCIe) adapter card that adds two RS-232 serial ports (DB9) to a computer. It is often sold under brands like Exone , DeLOCK , or Manhattan . The card is based on the Oxford Semiconductor (now part of Diodes/PLX) chipset, typically the OXPCIe952. Drivers and Installation For the "driver upd" (Update) part of your request:
A: Some industrial drivers require a paid license for advanced features or real-time extensions. Contact your hardware vendor. remove: sudo rmmod pi40952_driver It looks like you’ve
Once the driver installation status registers as "This device is working properly," multi-IO serial, parallel, or specialized USB express cards require custom parameter calibration to prevent buffer overflow and frame drops: Configuration Parameter Target Selection Setting Operational Impact Match peripheral speed (e.g., 9600 or 115200 ) Standardizes raw data transmission timing boundaries. FIFO Buffers Maximum Value Available ( 128-byte / 256-byte ) Minimizes CPU context switching over expansion buses. Flow Control Hardware (RTS/CTS) or Xon/Xoff
This refers to the core network controller board or the specific print engine processing unit. It manages internal page description languages (PDLs), memory allocation, and data conversion.
