Hi Mikie,

I'm very familiar with RS-232, been using it since the late 1970's, back when it was only a DB-25 connector. Then IBM co-opted the DE-9 connector in the PC-AT, and all the hardware illiterates erroneously called it a DB-9. Been writing serial comm code for 40-some years.

I don't see a way to specify "serial component" in PEP1 database, and command codes are IR only. Is this feature only in PEP2 or later?

There is only a "RS-232 command" action that lets you set the serial port number, but its not part of the database and not directly associated with a component.
