Sierra Router
Command
** Sx, y, z !!
x= Source number
y= Destination
z= Router level (Usually 1)
Note- to program the current custom serial, I had to alternate between hex and Ascii. When I tried to input the commas and other symbols as text, I couldn't. Ended up inputting those as hex values and putting in the Sx y and z as text.
Looks like: [2a][2a]'s1'[2c]'1'[2c]'1'[21][21]
This switches source one to output one on router level one.
