Document Type and Number:
Japanese Patent JP3202693
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a full duplex/half duplex automatic discrimination device.
SOLUTION: When a 1st discrimination section 12 receives an initial communication packet sent from an opposite device, a transmission section 13 transmits a pseudo packet to the opposite device. In the case that a 2nd discrimination section 14 detects collision, a communication mode formal setting section 15 sets the half duplex mode formally. On the other hand, in the case that the 2nd discrimination section 14 detects no collision, the communication mode formal setting section 15 sets the full duplex mode formally.
