Note: The DMD2401 Satellite Modem constantly asserts the DM/DSR Signal (DM and
DSR are actually the same signal). The modem is always in the condition of being able to
accept data. DTR Input to the modem is not necessary and is ignored. The DM/DSR
Output of the modem is located on Pins 11 and 29 as shown above.
