Hello CS100 users,

     We installed Version 12010 of the bridge CS/100 TCP/IP software a few
weeks ago. I was wondering if anyone else has seen the problem illustrated
below ? It seems that the CS/100 is sending invalid IP and TCP packets.
This only occurs on sustained output. The invalid packet is retransmitted
several times in it's invalid state. After a while, about 1 minute, the
packet is retransmitted correctly.

     CFB/IN - packets arriving at the PC from the CS/100
     CFB/OUT - packets from the PC to the CS/100

P.S: I re-installed Version 12000 and everything was correctly.
