FlyHLLAPI supports a limited subset of the OIA information area.
In the returned data string, position one will indicate the session type as follows:
1= TN3270/TN3270E session
9= TN5250 session
V= TNVT session
In the remaining string, only position 92 is set to anything other than a NULL, and it follows the CLOCK which is turned ON in-between screen transitions and is then controlled afterwards by the host.
When the clock is ON, position 92 will contain a blank. When the clock is OFF, position 92 will contain a null (0) character.
