Our BCP implementation doesn't do TEXT columns.  Neither does it complain; it just hangs because the server doesn't respond.  

For your enjoyment, attached is tcpdump output of an upload to a table having a single column, of type TEXT.  The tools used were:

$ bcp -v
BCP - Bulk Copy Program for Microsoft SQL Server.

Version: 7.00.623

$ isql -E -Smpquant -Q"select @@version"
 Microsoft SQL Server  2000 - 8.00.818 (Intel X86)

$ windump -w textbcp.tcpdump -xX -s1500 tcp and host mpquant and port 2500 and host ntc0272

I thought perhaps we could at least decode what's going on.  That would make it easier to add the functionality.  

Thank you for your kind attention.
