In gtkterm, this works.  The data is returned immediately.

You don't need to press <enter> in gtkterm to get the response? Most serial 
controlled instruments require newline to accept command:
srl_write(s1, "ID?\n")

Actually, what works best is "cmd\r\n" The TEK TDS-2014 is set to RS-232 EOL, not CR-EOL. Strange
