i think it is even easier to set the state up properly with cpurc or
consolefs' configuration file, and have the various programs not even
care that they're talking to a serial port.

rdb, for example, was one program that got this wrong.  it was setting
the baud, which backfired in some cases.  not doing anything is a better
solution.  you can always echo bxyz>/dev/eiaXXctl, assuming it really
is a serial line.  :-)
