Thanks! It does indeed do the trick! With that I was able to

  1. Obtain current exposure value using the terminal command caget C1:CAM-ETMX_EXP
  2. Set exposure value using the terminal command caput C1:CAM-ETMX_EXP <desired_exposure_value>

Further, a quick look at the camera server code in /opt/rtcds/caltech/c1/scripts/GigE/SnapPy_pypylon/camera_server.py revealed that the script expects the details of "Number of Snapshots" in "Camera Settings" in the configuration file i.e in C1-CAM-ETMX.ini at ( /opt/rtcds/caltech/c1/scripts/GigE/SnapPy_pypylon/C1-CAM-ETMX.ini) which wasn't present before. Adding this parameter to the config file allows one to take a snapshot using the medm screen. Infact, unlike as described in this elog, I was able to start the server and client as described in elog 14649, and then obtain snapshots using the terminal command  caput C1:CAM-ETMX_SNAP 1.

caget/caput probably does the job.

Still not sure about how to modify the exposure time (other than using the pylon app, the only technique I know so far is to adjust the exposure manually on the medm screen and then run the scripts as described in the previous elog).
