patch for connection of nokia 3220 via CA-42 cable

[Burkhard Soehne]

Hello,

with this small patch I can use gnokii on my 3220 without constraint. I've 
analyzed the traffic between Nokia PC Suite and the phone. The very first seq 
id sended from the software is always or-ed with 0x20 (the result is 0x60 
instead of 0x40).
Even if there comes a (rare) seq error (0x80) from the phone while working 
with Nokia PC Suite, next seq from the Suite will be 0x60.
Perhaps this patch will connect a few more phones to gnokii.

Hardi
