You can make your life a bit easier by running mode.exe from an OS/2
session, immediately after booting your machine.  You'll get a display
similar to the one below, then you can see those which are already the
system defaults, which will save you deleting them unnecessarily from your
mode command.

[OS/2] D:\>mode com2
baud     = 57600                  parity   = NONE
databits = 8                      stopbits = 1
TO       = OFF                    XON      = ON
IDSR     = OFF                    ODSR     = OFF
OCTS     = ON                     DTR      = OFF
RTS      = HS                     BUFFER   = ON

These are not the defaults, as I'd already set up the port previously.  My
own successful mode command is...

MODE COM2:57600,N,8,1,DTR=OFF,RTS=HS,OCTS=ON,TO=ON,XON=OFF,BUFFER=ON

Anything not specified system-default to the settings I need to use.
