Putty Serial Connection problems

Hi forums,

I was wondering if any of you have faced this problem that I have been having for quite some time now regarding serial connection with putty to my Solaris Box Sunfire v250 and Sun v220 and sun v440.

The serial connection freezes on my Windows 7 64 and 32 Bit machines.
I unplug and plug it back in and try to reconnect the connection only to get an error message "Unable to open connection"
The only remedy was to force restart my Windows 7 machine.
Is there any processes or services I can force it to shut down rather than force rebooting my Windows machine every time this happens?

I also notice in my device manager when the Serial connection freezes the "COM4 serial to Bridge" device is no where to be seen.

I am using putty version .62
Serial: COM4
Speed: 9600
Data bits: 8
Stop bits: 1
Parity: None
Flow control: XON/XOFF

Thank you very much Smilie

NAME
SynCE - A project for connecting to devices running Microsoft Windows Mobile. DESCRIPTION
The SynCE project aims to provide libraries and tools to connect to and synchronise with PDA's and other devices running Microsoft Windows Mobile, or Windows CE. The main components include :- libsynce Core library that provides various support services and functions. librapi2 Core library implementing the RAPI protocol, equivalent to rapi.dll on a Windows OS. RAPI is used for most kinds of interaction with a WM device. This library actually implements two versions of the protocol. RAPI 1 is used for devices up to and including CE 5.0, with RAPI 2 coming into use from 5.1 (WM5). librra Library implementing RRA (Remote Replication Agent), a protocol used for synchronisation. This protocol is used for all data synchronisa- tion until WM5, at which point Airsync is used for the majority. RRA is still used for file synchronisation however. dccm The dccm daemon negotiates the initial connection with a WM device, and may provide keep-alive signals and client connections, depending on the device version and flavour of dccm. There have been a number of dccm 'flavours'. The original, also known as synce-dccm, is now considered obsolete and should not be used. Vdccm is a natural progression of dccm which is not greatly used anymore. Odccm is the most common in use at the moment, and uses dbus to provide connections to both legacy and modern devices. Hal-dccm is a new option that integrates the dccm functionality into hal to provide a more platform consistent interface. The following steps are required to get started with SynCE: (1) Ensure the rndis kernel module or a serial connection mechanism is installed To use advanced network features (rndis) with a WM5 or later device, which is recommended, you must use the usb-rndis-[lite|ng] driver from SynCE. For older devices or to use serial with WM5, if synce-hal is not used you will require the synce-serial package. You will of course also need a dccm daemon, synce-hal or odccm is recommended. (2) Start the connection daemon (as root) If using odccm, this daemon must run as the root user. With synce-hal, dccm will be started as required. Older dccm implementations must be run as your user. (3) Run tools that access the device (as user) See for example pls(1) and pcp(1). See http://www.synce.org/ for more information about the SynCE project. AUTHOR
