fix for GSMTestModem not working about gsm

[GeraldSoellinger]

I experience a similiar problem with Arduino IDE 1.8.5. I tried also different GSM libaries (version 1.0.0, 1.0.5 and 1.0.6), but still the AT commands look different compared to Arduino IDE 1.0.5-r2 e were everything seems to work.

here some section of my code:
Serial.println("GSM initialized");
Empfangsstaerke = scannerNetworks.getSignalStrength().toInt();
Serial Monitor output with IDE 1.0.5-r2
AT+COLP=1%13%
74 80>%13%%10%OK%13%%10%
GSM initialized
AT+CSQ%13%%10%Empfangsstaerke: 21
Serial Monitor output with IDE 1.8.5 and GSM libary version 1.0.6
AT+COLP=1%13%
102 108>%13%%10%OK%13%%10%
GSM initialized
A%13%Empfangsstaerke: 0

I made a new finding today. I removed the original GSM libary from IDE 1.0.5-r2 and replaced it with the GSM libary form IDE 1.8.5 which has version number 1.0.6
Serial Monitor output withIDE 1.0.5-r2 and GSM libary version 1.0.6
AT+COLP=1%13%
67 73>%13%%10%OK%13%%10%
GSM initialized
AT+CSQ%13%%10%Empfangsstaerke: 22

So it seems, there is no problem with the libary, but somewhere with the new IDE

Where can/should I report this issue with the IDE?

Between 1.0.5-r2 and 1.8.5 is a huge jump. You need to bisect the issue to see exactly where it was introduced. Go back to using Arduino IDE 1.8.5 and using Boards Manager (Tools > Board > Boards Manager) to systematically roll back through the available versions of Arduino AVR Boards until you determine which is the newest version that doesn't have the issue and the oldest version that does have the issue. Then you know the cause of the issue is something that changed between those two versions. That narrows the scope tremendously.
