      No, the schematic's right.  The names of the pins on CN1 and CN2 are established by the DR-135T service manual.  TXD and RXD are relative to the TNC, not the radio.

      Scott,

      While going over the T2-135 schematic diagram one more time, paying
      attention lines from 2211 chip to the CN2 connector, I felt that the
      designations for P10 and P11 should be the opposite.
      Is my observation correct?

      thanks, Paulus
