FarSync Drivers

 New Features

Async Features

This release introduces Async operation on FarSync Flex, T4E, T4E+ and T4U cards that have been fitted with Async components.  The Async functions can be accessed programmatically via standard tty function calls or through the FarSite Char API.  The features supported in this release are:

The minicom terminal emulation application is able to open a session and operate over the async port.

The xmodem application is able to transfer files over the async port.

The Linux async PPP Daemon is able to use the FarSync async ports for ppp sessions.

More details about using the async port are available here.

New Card Supported

This releases introduces support for the FarSync T4E+ card.  This is an enhanced version of the T4E that includes support for Manchester encoding in addition to nrz.

The farmon Utility

The farmon utility is now installed as a command.

The farnetd Line State Monitor Daemon

The farnetd utility is now available for most devices.

Custom Data Rates

The T4E card supports generation of a large number of standard clock rates.  The clock synthesiser on the T4E card can be set to generate almost any specific clock rate not available as standard through use of a new configuration parameter, "synth".  For details on how to use this parameter see the configuration section of the documentation.

New Configuration Parameters

synth data string supplied by FarSite flow_control hardware or software or none
NRZIClocking enable or disable stop_bits 1 or 1.5 or 2
termination resistive or none parity odd or even or none
lineMode hdlc or transparent or async word_len 5 or 6 or 7 or 8
numRxBuffers Same as numBuffers.  It just allows rx to be configured individually xon_char  
numTxBuffers Same as numBuffers.  It just allows tx to be configured individually xoff_char  
sizeRxBuffers Same as sizeBuffers. It just allows rx size to be configured individually    
sizeTxBuffers Same as sizeBuffers. It just allows tx size to be configured individually    
encoding the value of Manchester has been added to this parameter    

Dependence on syncppp Removed

The FarSync OEM driver no longer connects to the syncppp module.  Therefore the syncppp.c source file is no longer required in order to complete the OEM installation.
