from netbsd uplcom.c revision 1.37:

Make sure that we call uplcom_set_line_state() to get consistent state
between our idea of flow controll settings and the chips one.
In uplcom_set_line_state use the same value as the manufacturer suggests,
since the previously used (umodem based) values do not seem to work.
It is not completely clear what happened here - either the "not calling
uplcom_set_line_state" due to luck prevented the non working state to
be discovered or there are variants of the chip that need the old values.
During testing none such chips have been found - if they ever apear we
might have to make this function more intelligent, depending on the chip
in use.
