the 3 speeds under test.  Default = 3.
Phytest
Limits the test to just one speed which can
be set with /BAUD.  It also uses all null
bytes rather than random data.  Default
speed = 115200 baud
Valid Keystrokes
Action
any key
Any keystroke will abort The Full 2 Unit IR
test.

RS-232 Port - 
(RS232.COM)
N
OTE
:
This test requires a serial loopback connector to be connected to the serial
port.
The RS-232 Port test reads/writes to the COM1 serial port IER, baud divisor registers, and LCR.
It also checks for the loopback connector and sends a byte through the loopback connector at
each of the baud rates.  The RS-232 Port test is hardcoded to test the UART at 3F8, therefore, it
can test only COM1.
DOS Parameter

Valid Keystrokes
Action
