Explanation
One of the most popular forms of communication between electronic
devices is serial communication. There are two major types of serial
communication; asynchronous and synchronous. The SERIN and
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. Please read through the SERIN command
section for additional information.
All BS2 models have a line driver on its SOUT pin (Tpin = 16). 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 BASIC Stamp 2 Carrier Board (#27120) which is only designed for
programming). For the built-in serial port set the Tpin argument to 16 in
the SEROUT command.
