TLS connection issue. Works with config file but does not work with parameters.

[olidel001]

My issue is with TLS connection. Basically when I'am using a configuration file it works fine but when I'am using parameters on the p3270Client method then it doesn't work and the connection just fail. You will find below a trace with the 2 scenarios.

My python application to use directly the x3270 application that you have created and I have some issues with TLS connections. Basically, when I'am using a config file it works fine as what the debug output below shows:

Python instruction: client = p3270.P3270Client(configFile=cfgfile)

cfgfile =

hostname = x.x.x.x
port = 992
model = 3279-2
codePage = cp037
enableTLS = yes
verifyCert = yes

Debug output:

When it does not work I have this from the command line:

Python instruction: client = p3270.P3270Client(hostName='x.x.x.x', hostPort='992',configFile=None, verifyCert='no', enableTLS='yes', codePage='cp037', path=None, timeoutInSec=20)

**Connection failed !</module>**

As you can see above there is a difference in the parameter that are passed. The '-noverifycert' is not passed to the module. So, I believe this is why it does not work. I would rather pass the parameter through the class/method call rather using a configuration file as this make things a bit more complex.
