BCP stops after the last “1000 rows sent to SQL Server. Total sent: …”

Question

I ran SQL Server 2005's bulk copy program BCP like this:

bcp mydb.dbo.mytbl in myfile.blk -c -S mysvr -U mylogin -P mypass

And it ran and produced output like so:

Starting copy...
1000 rows sent to SQL Server. Total sent: 1000
...
1000 rows sent to SQL Server. Total sent: 55000

But then it stopped. The cursor did not return to prompt, I haven't received the "... rows copied." message.

I tried querying the target table and I can already see the rows that I wanted to import.

Shall I terminate the console? Will it rollback?
