Q22. Do Quatech USB to Serial Adapters contain USB hubs as well as serial ports?

USB Serial Adapter FAQs by Quatech
No. Quatech USB to serial adapters do not also included hubs. However, you can purchase third-party USB hubs to add additional USB ports to your system. The maximum data rate for USB 1.1 is 12 Mbps. USB 2.0 devices are capable of speeds up to 480 Mbps. Quatech USB 1.1 compatible serial adapters can reach speeds of 460.8 kbps--more than fast enough for most serial peripherals. Thus, there would be no advantage to implementing USB to serial adapters on the USB 2.0 standard. No.

How do I add serial ports to my PC/104 system?

PC/104 Embedded Systems FAQ, EBX, Linux, Real Time, data acq...
PC/104 systems treat serial ports as do ISA bus systems. All you need is a serial communication module that is compliant with the PC/104 bus architecture. There are usually no special steps involved in configuring the port, other than the standard port address/IRQ jumper settings often found on the module. Once the module is plugged in the stack, any communications software will be able to access the module in the same way it would be accessed if it were an ISA bus serial port.

How can several serial ports share the same IRQ?

PC/104 Embedded Systems FAQ, EBX, Linux, Real Time, data acq...
There are two basic ways to do this. A simple but inefficient method is to set each port to the same IRQ and poll each port every time an interrupt is generated. Analogy - Imagine paging each of 8 employees offices to find out who paged you on the intercom. This is an example of polling. Each port/office gets checked but it takes time. The more efficient method is to have an Interrupt Status Port onboard the module. The interrupt status port tells you which port(s) generated the interrupt.

This error was due to a bug in the serial drivers. A fix has been made, but it did not make it into the 1.1 distribution kernel. Kernels since that time should have the fix incorporated.

The current source on ftp.netbsd.org should be correct.
