Micro Digital rolls USB multiple virtual serial port solution for embedded systems

Costa Mesa, Calif. — Micro Digital Inc. has released a USB multiple virtual serial port (MVSP) solution for embedded systems. The MVSP consists of a multiple serial port function driver that operates with Micro Digital's smxUSBD USB device stack in the embedded device, and a custom multiple serial port class driver that runs with the Windows USB host stack. This means when the embedded device is connected to a Windows computer, multiple USB virtual serial ports will be recognized and a Windows application can communicate with each of them independently.

Some applications use this capability to connect to multiple UARTs in the embedded device's processor. Other applications use virtual serial ports to connect to memory or other units within the embedded device, which can be used for gathering information or testing the embedded device.

By using the Micro Digital Composite USB Device Framework, the MVSP can be combined with other USB function drivers such as mass storage. Micro Digital also offers function drivers for Ethernet over USB (RNDIS), which allows accessing a web server in the embedded device without an Ethernet or PPP connection, and audio with a MIDI connection.

Pricing: A single-product, royalty-free license is priced at $2,000 and $4,000 for the smxUSBD.
Availability: The MVSP is available now.
Product information: smxUSBD
