DTE/DCE mode
Each serial port can be configured to connect to a terminal (DTE
equipment) or a modem (DCE equipment). Instructions for configuring
the DTE/DCE switches SW2, SW3, SW4, SW5, SW6, SW7, SW8, and
SW9 are shown in
Table 41 "QSDI paddle board DTE/DCE mode switch
Example: Port 1 is changed from DTE to DCE by reversing every switch
position on SW3 and SW2; that is, switches that were off for DTE are
turned on for DCE, and switches that were on for DTE are turned off for
DCE.
