Problem:
'bs11_config' can't get a connection to the BS-11 (no 'LMT LOGON: ACK')

Solution:
The BS-11 is a little bit choosy about the RS232 levels, I discovered some problems
with my Dell PC (could receive anything, but no tx). Just switch to an el-cheapo USB
to Serial adapter, this should solve the problem.

Some background notes:
We measured the RS232 levels and we found out that the level of our RS232<==>USB Adaptor
is much lower (about /-6 Volts) than normaly expected (/-12V). The BS11 transmits at a
semeliar level (about 8 Volts). This may be an explaination why the BS11 does not like
the normal (+/-12V) levels. See attached files (Lmt_*) for oscilloscope screenshots.
