Example in Quick-Basic of how to transmit and receive COMPAX data via the RS232 interface.

DIM text$(30)	´	The text string "text$" is defined with a length of 30.
a$="com1:9600,N,8,1"	´	The interface parameters are assigned to the "a$" string. Meaning:
	´ com1:the com1 serial interface is used.
	´ 9600: sets baud rate to 9600
	´	N:	no parity
	´	8:	8 bit word length
	´	1:	one stop bit
OPEN a$ for RANDOM AS #1	´	The interface is initialized and marked with #1 (channel 0).
text$="S1"	´	Status S1 must be queried.
PRINT #1,text$	´	text$ is output on channel 1.
text$=""	´	text$ is deleted so that the response can be accepted.
INPUT #1, text$	´	S1 is read by channel 1 in text$
PRINT text$	´	S1 is output on screen
