I believe your version of caput is out of date. The newer
version of caput will accept the negative value directly.
( The newer version needs to set the environment
variable LD_LIBRARY_PATH on the solaris system. )

For your information, the newer version of caput command
syntax is given below:

kao 49: caput

Usage:  caput [-t] [-s] [-w sec] [--] pv_name  pv_value

This command writes a value or array of values to a channel.
It can also write an array of single values to an array of channels.

        -t   Terse mode, only the successfully put value is returned
        -s   pv_value entered as database defined enumeral string
    -w sec   Wait time, specifies bigger time out, default is 1 second
        -m   this option specified the input value string is 
             a comma separated values for a waveform record 
   pv_name   requested database process variable name
             (multiple PV names must be seperated by comma no space)
   pv_value  new value to put to IOC
             (multiple PV values must be seperated by comma no space)

  Examples:    caput  pv_name  pv_value
               caput  pv_name1,pv_name2   pv_value1,pv_value2
               caput -m  pv_name  v1,v2,v3,...
