Writeread - Mini-Circuits ISC-2425-25+ Quick Start Manual

When the 'Set Frequency' button is pressed, the string "$FCS,0," is concatenated with the contents of the lineEdit
'lineEdit_frequency" and is sent to the ISC board. E.g., $FCS,0,2450.
Most commands reply with only one line. For example:
> $IDN,0

< $IDN,1,Mini-Circuits,ISC-2425-25+,MN0003402112
> $PWRG,0

< $PWRG,1,10.000000
> $ECS,0,1

< $ECS,1,OK
However, a small handful of commands return more than a single line. For example, the verbose version of the 'Status
Get' command:
> $ST,0,1

< $ST,1,RESET_DETECTED
< $ST,1,EXTERNAL_SHUTDOWN_DETECTED
< $ST,1,OK
To handle these two different types of responses, there are two separate functions for sending commands and receiving
responses:

writeRead


writeRead_OK

3.4.1 writeRead
The 'writeRead' function is used for commands with single-line responses. Here's a
breakdown down of the function:
1. It takes the command string for the signal generator as an argument, checks whether the SG_port is still open at all
before continuing, and then prepares a QString 'rx' in which to store a response to the command.
