Programming example

The following QuickBasic 4.5 programming example will control the SourceMeter via the
RS-232 COM2 port. Place the SourceMeter into the RS-232 mode from the front panel main
menu (press MENU, select COMMUNICATION, select RS-232). When the communication
setting is changed, the SourceMeter will reset into that mode.

PRINT "Set COM2 baud rate to 9600"
PRINT "Set no flow control, and CR as terminator."
' Configure serial port parameters.
' The following values are the default settings for the SourceMeter:
ComOpen$ = "COM2: 9600,N,8,1,ASC,CD0,CS0,DS0,LF,OP0,RS,TB8192,RB8192"
OPEN ComOpen$ FOR RANDOM AS #1
