I have a serial device for which I am trying to implement Device Support using ASYN. This is an EOS-901 from Eye on Science, a VAC ION Pump controller. There is one parameter, the Soft_Current_Trip_Level that requires the following procedure: 1) Send: "UHV99S" (constant string) 2) Read: "Enter Alarm Limit\r" (the unit will now wait until a new value is sent as follows) 3) Send: "0.000001\r" (value dependent string) 4) Read: "new limit=1.00e-06\r" I can write a GPIBCVTIO routine that will accomplish all four steps. Am I correct in assuming that no other gpibCmd for this device will process while my gpibCmd with the GPIBCVTIO routine is executing? i.e. the four steps cannot be interrupted by a request from some other periodically scanned record associated with this device? Thanks, John Dobbins Laboratory for Elementary Particle Physics Cornell University Ithaca, NY
