If the array is already containing the ASCII code for the character you want to send then that will work but by your description and code it sounds like the array can contain values from 0-255 and that it is the decimal representation of those values you want to send - as ASCII?

Ie. if the array contains the value 65 it's '65' you want to see on your terminal - not 'A' which is the ASCII character for the decimal value 65.

Perhaps what you're looking for is more in the line of:
Code:
Main:
  if track=0 then
    rot1time=1
    rot2time=2
    rot3time=3
    rot4time=4
    rot5time=5
    rot6time=6
    rot7time=7
    rot8time=8
    rot9time=9
    rot10time=10

    FOR i = 0 to 0                     
      hserout [DEC rottime[i]]
    NEXT
    HSEROUT[10,13]

    pause 500 
  endif
