Attribute Summary:

Description:

This command specifies the handshake type when the analyzer is sending data.

XON specifies the XON/XOFF protocol. The peripheral device must send XOFF (DC3, decimal code

19) to the analyzer to stop the transmission of data. When the peripheral device is ready to accept more

data, it must send XON (DC1, decimal code 17) to the analyzer, which then resumes transmission. This

software handshake is the easiest to implement.

DSR specifies a hardwire handshake. When the peripheral device is able to receive data, it sets its Data

Terminal Ready line true (high). This sets the analyzer's Data Set Ready (DSR, pin 6) line true. When

the peripheral device is not able to receive data, it sets its DTR line false (low). The analyzer will not

send data until the peripheral device's DTR line is set true.

NONE specifies the absence of a handshake protocol for pacing.

Check the documentation for your peripheral device to verify it supports the specified protocol.
