Function

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

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

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

set to input mode. On all BS2 models, if Rpin is set to 16, the BASIC

Stamp uses the dedicated serial-input pin (SIN, physical pin 2),

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 indicate flow control status on. This pin will

be set to output mode.

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

65535 on all BS2 models) that specifies serial timing and

configuration.

• Qualifier is an optional variable/constant (0 – 255) indicating data

that must be received before execution can continue. Multiple

qualifiers can be indicated with commas separating them.

• Plabel is an optional label indicating where the program should go

in the event of a parity error. This argument should only be

provided if Baudmode indicates 7 bits, and even parity.

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

tells SERIN how long to wait for incoming data. If data does not

arrive in time, the program will jump to the address specified by

Tlabel.

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

indicating where the program should go in the event that data does

not arrive within the period specified by Timeout.

• InputData is list of variables and formatters that tells SERIN what to

do with incoming data. SERIN can store data in a variable or array,

interpret numeric text (decimal, binary, or hex) and store the

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 InputData argument

can only be a list of variables and the

optional decimal modifier (#).
