glynnmsg,
I have never done the download to an Option 81. However, you might try the following script file.
proc main
string DateString, TimeString ; Time and date strings.
; Convert long time into date and time, in text form,
; and display it on the status line.
ltimestrs $LTIME DateString TimeString
usermsg "DATE IS: `"%s`"!" DateString
usermsg "TIME IS: `"%s`"!" TimeString
endproc
Remove the usermsg and replace with transmit commands.
For example replace
usermsg "DATE IS: `"%s`"!" DateString
With
transmit DateString
See how that works.
