User’s Manual
5.2.1 The first page is to set the host baud rate and the hardware flow control.
Please Note:
Ignore CTS: If host device has no hardware flow control signals, only Tx, Rx and GND, then you
have to set this bit to 1. IR100SD will pass the coming data to host and doesn’t care the
status of CTS. Note: Since IR100SD is a buffer limited dongle (2K bytes for host and 2K
bytes for IrDA), if this bit is set, then it will cause data loss (Because no flow control).
Where data loss can be solved if user sends data by segment and every segment
doesn’t exceed 2K bytes.
Ignore DSR. If host system has no DSR signals, then this bit should be ignored. But since this signal
triggers IR100SD into Primary mode, it will be no way to ask IR100SD disconnecting
IrDA link. And IR100SD will always be in Primary once power on. In other words, once
D4 is set to 1, you are not able to control IR100SD at all until power off and reset D4 to
0. This bit is recommended being set when host device is in Secondary mode.
