Sometimes the line that PM iSeries™ uses is in the connect pending state. This state does not allow PM iSeries to access the line to transmit data.
The PM eServer™ iSeries Line Control display allows PM iSeries to vary off the line, transmit the data, and then put the line back in the connect pending state. When you use this display, you can change the PM iSeries transmission task (Q1PCM1) to check for line status and vary off the appropriate line. Once the transmission is complete, the same line is placed in a connect pending state.
To vary off and on a line, do the following steps:
You can also set up PM iSeries line control by using the Configure PM eServer iSeries (CFGPM400) command.
