How do I create a ‘silent install’ for a Sealevel software driver in Microsoft Windows?
All current Sealevel software packages can be silently installed by running the installer with the /S /v/qn command line switches. This is demonstrated for SeaCOM…
Where do I find a Linux driver for my Sealevel asynchronous serial adapter?
Most Sealevel serial adapters use the serial drivers built into the Linux kernel. For USB and UART-based serial adapters, the Linux drivers may need additional…
How to add missing vendor/product IDs for UART-based serial adapters in Linux
Linux supports the direct use of 16XXX UART-based devices with the drivers included in the kernel sources. However, kernel versions prior to 3.7.0-rc6 are missing…
How to configure USB serial adapters in Linux
