(SP) Serial Port – This command configures the serial communication port(s) as
follows:
Table 5-12: Serial Port Configuration Set Command

For EX2 models the data length, parity, and stop bits are fixed at 8, N, and 1
respectively. And, for Applicator Interface Card-equipped models, this command is
also used to configure the GPIO Auxiliary port (ID always “B”).
Example:
<STX>KcSPAPB;SPApN;SPAD8;SPAS1;SPAB19<CR>
The example above configures Serial Port A to use hardware and software
handshaking, an eight-bit word, with no parity and one stop bit at 19,200 bits per
second.
