SEROUT Tpin, Baudmode, ( {#} OutputData )

SEROUT Tpin { \Fpin }, Baudmode, { Pace, } { Timeout, Tlabel, } [ OutputData ]

Function

Transmit asynchronous serial data (e.g., RS-232 data).

• Tpin is a variable/constant/expression (0 – 16) that specifies the I/O

pin through which the serial data will be transmitted. This pin will

be set to output mode. On all BS2 models, if Tpin is set to 16, the

BASIC Stamp uses the dedicated serial-output pin (SOUT, physical

pin 1), which is normally used by the Stamp Editor during the

download process.

• Fpin is an optional variable/constant/expression (0 – 15) that

specifies the I/O pin to monitor for flow control status. This pin will

be set to input mode. NOTE: Fpin must be specified to use the

optional Timeout and Tlabel arguments in the SEROUT command.

• Baudmode is variable/constant/expression (0 – 7 on the BS1, 0 –

65535 on all BS2 models) that specifies serial timing and

configuration.

• Pace is an optional variable/constant/expression (0 – 65535) that

determines the length of the pause between transmitted bytes.

NOTE: Pace cannot be used simultaneously with Timeout and Fpin.

• Timeout is an optional variable/constant/expression (0 – 65535) that

tells SEROUT how long to wait for Fpin permission to send. If

permission does not arrive in time, the program will jump to the

address specified by Tlabel. NOTE: Fpin must be specified to use

the optional Timeout and Tlabel arguments in the SEROUT

command.

• Tlabel is an optional label that must be provided along with Timeout.

Tlabel indicates where the program should go in the event that

permission to send data is not granted within the period specified

by Timeout.

• OutputData is list of variables, constants, expressions and formatters

that tells SEROUT how to format outgoing data. SEROUT can

transmit individual or repeating bytes, convert values into decimal,

NOTE: Expressions are not allowed as

arguments on the BS1. The range of

the Rpin argument on the BS1 is 0 – 7.

NOTE: The BS1's OutputData

argument can only be a list of variables

and the optional decimal modifier (#).
