ASYN Question

[John Dobbins <jad@lepp.cornell.edu>]

Dear All,

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,
