Debugging the DTE interface
A hardware-based serial RS232 monitoring product, such as the "Parascope Plus", is an invaluable tool for
debugging the DTE/DCE Interface. It captures and records details of DTE - DCE interaction. Hex and bit-shifted
views are possible, and it timestamps every char exchanged with much higher accuracy than a software-based
monitor. It is sold by FETEST http://www.fetest.com.
