CLS ‘Clears the PC screen.
OPEN "COM1:1200,N,8,1,CS,DS,RB2048" FOR RANDOM AS #1
PRINT #1, "WT 15,28,0" ‘Sets the real time clock to 03:28 p.m..

‘ScopeMeter. This routine inputs the acknowledge response from
‘the ScopeMeter. If the response is non-zero, the previous
‘command was not correct or was not correctly received by

‘the program is aborted.
Acknowledge:
INPUT #1, ACK ‘Reads acknowledge from ScopeMeter.
IF ACK <> 0 THEN
