#Serialport x code

For source code compatibility with Sun’s API, we can not do it the correct way. The correct thing to do is to throw an UnsupportedCommOperationException however, Sun’s API does not define this. setDTR on UnixWareIA32) a message similar to the one shown below will appear on the console: When using our implementation on a platform that does not support one of these features (e.g. Likewise, notifyOnCD, and notifyOnRingIndicator make no sense on the Mac. For example, Macintosh hardware does not have DSR or RTS hardware so isDSR and setRTS make absolutely no sense on the Mac. Since the Comm API does not provide this feature, it should at least define some of the methods to throw unsupportedCommOperationException. The SerialPort product does this with the ‘isSupported’ methods. There should be some way to determine if some set/is?, and notifyOn? API methods are supported. Many of the issues reported were apparently ignored by Sun, as those issues still remain with the Comm API in the initial release (long after the issues were reported). When Sun released the first early version of the Comm API Solutions Consulting implemented that API using SerialPort and reported these design problems with the API. The implementation of supports JavaPOS. This can occur for example, when hardware flow control is selected, but no hardware is present, or the client has flow control disabled indefinitely. This means that threads that transmit data using, can potentially lockup. ** provides the method enableReceiveTimeout, however, does NOT provide the parity method enableTransmitTimeout. Selectable blocking at Java or Native level

#Serialport x serial

API FeatureĪPM CF slot status (detect CF serial port)įlexible ‘isSupported’ cross-platform feature implementation The CommConnection API is even more restrictive than the API, and requires the developer to learn another API only to be limited by its design.

The m API design is insufficient for such flexibility therefore the CommConnection interface was developed to replace m on MIDP.

Developers using the SerialPort API can use the same powerful API for all their target devices, from Super Computer class to MIDP class devices. The original SerialPort design was robust enough to port to J2ME MIDP on WME. If you code your solution with the SerialPort API, use the same code on both MIDP and non-MIDP environments. If you use CommConnection, you may have to recode your solution to run on a non-MIDP environment. SerialPort provides a very flexible solution, and provides a consistent API across all devices.ĭid you know you may have to code your solution twice? If you use you may have to recode your solution if you want to run it on MIDP. As diagrammed below, the implementation of was built completely using the SerialPort API and is based on the Comm API 2.0 (the first release in spite of the version number). The SerialPort API was shipping commercially for about 18 months before Sun introduced. SerialPort provides maximum flexibility (evident by the fact that is implemented entirely using SerialPort). This information will help you determine if you wish to use the superior SerialPort API directly, or the API.

People frequently ask if SerialPort provides support for.
