The telnet server includes a loop command that can be used to iterate a given command. The number of iterations and the delay, in ms between two iterations can be modified, as shown in the following example:
softmodem> telnet get loopc
telnet, loopc = 10
softmodem> telnet get loopd
telnet, loopd = 2000
softmodem> telnet set loopd 1000
telnet, loopd set to
1000
softmodem> loop softmodem show thread
