ATTENTION: With eor and eof set to 0, any readln() call
you make in applications never terminates. Use the raw read()
call to read from the serial ports.
Use the OS-9 system management utilities tmode and xmode to set
up or view the communication parameters for the control-coprocessor
serial ports.
Use this mode: To display or:

If you have an application that was designed prior to release 1.3 and you
require the original settings of the serial port COMM1, for example,
include xmode commands in the startup file with the following argument:
xmode /t1 normal
This returns the serial-port settings to the settings used before firmware
release 1.30. See the next section for a description of CC_VALCOMM, a
utility that saves the changes made after an xmode operation and retains
the changes over power cycles.
See Figure 7.1 for the default settings for tmode and xmode.
