You can omit unneeded commands, and repeat needed commands. You can also increase waiting times.
For my system (external multiswitch),
S13E 11700 V 9750 t v [E0 10 38 F4]
S13E 99999 V 10600 t v [E0 10 38 F5]
S13E 11700 H 9750 t V [E0 10 38 F6]
S13E 99999 H 10600 t V [E0 10 38 F7]
works fine. But this does not mean that it also works for you ...
I always have t (tone off) because my multiswitch does not need the tone.
