Try lowering the and Transmit Buffer sliders slightly to improve stability with older hardware.
Once installed, the ASMedia ASM1083 Serial Port Driver provides reliable and efficient serial port communication. The driver supports standard serial port settings, including baud rates, data bits, parity, and stop bits, allowing users to configure the port to meet their specific needs. The driver also enables advanced features, such as hardware flow control and interrupt-driven I/O, which enhance overall system performance.
If your motherboard has an integrated ASM1083, go to the support page for your exact model. Search for "PCI Bridge Driver" or "Chipset Driver". For example:
Save your work and turn your computer off and on again. This makes sure the new software works perfectly. Fix Common Problems asmedia asm1083 serial port driver windows 10
