Longshine LCS-8240 / Netronix NH-240

[Volker Jahns <volker@thalreit.de>]

I do have here an Longshine LCS-8240, which seems to be a repackaged Netronix 
NH-240 ( MSP2006, 4M Flash, 64MB SDRAM - what Netronix claims) and which I 
would like to activate with homegrown Linux Firmware.

Is there any information out there for similar devices on
- howto to hook up a serial line
- firmware building and uploading

I have asked Netronix and Longshine for the source code, with Netronix
redirecting me to Longshine and Longshine not answering. 

Any help is much appreciated.
