Explanation
One of the most popular forms of communication between electronic
devices is serial communication.
communication; asynchronous and synchronous.
SEROUT commands are used to receive and send asynchronous serial
data. See the SHIFTIN and SHIFTOUT command for information on the
synchronous method.
The following information is supplemental to what is discussed in the
SERIN command section.
section for additional information.
All BASIC Stamps (except the BS1) have a line driver on its SOUT pin
(Tpin = 16). See the "Hardware" section of the "Introduction to the BASIC
Stamps" chapter. The SOUT pin goes to a PC's serial data-in pin on the
DB9 connector built into BASIC Stamp development boards. The
connector is wired to allow both programming and run-time serial
communication (unless you are using the Stamp 2 Carrier Board which is
only designed for programming). For the built-in serial port set the Tpin
argument to 16 in the SEROUT command.
