-o1 -o2 (don’t remember which is which)

From the docs:

-o options
Options:
0 – no compression.
1 – BPE (Byte-Pair Encoding) compression.
2 – RLL (Run Length Limited) compression.
8 – Use CRC (Cyclic Redundancy Check) error checking.


Combine options by addition, e.g. to specify BPE and CRC, select 9. If
the selected baud rate requires it, compression will be automatically
selected unless you specify 0.

Note:
The command-line options -t and -m turn on RLL compression by default.
The -m also turns CRC error checking on. To adjust these side-effects
you can use the -o option afterwards. For example, to run with no
compression when specifying a TCP/IP connection from the command line,
you would type: phindows -thost -o0.
