This command connects pins and instruments together using a specific pathway.

int conpth(int path, int connect1, int connect2, [connectn, [...]] 0);

You can force the system to use a particular pathway by using conpth instead of conpin. This

might be done to provide additional electrical isolation between two connections. The eight pathways

are numbered 1 through 8.

The first conpin or conpth command after any other LPT library call clears all sources by calling the

devclr command and then clears all matrix connections by calling the clrcon command before

making the new connections.

The value -1 for any item in the connection list is ignored by conpth and is considered a valid entry

in the connection list.

The conpth command is not valid in the row-column connection scheme. When the matrix is

configured for remote sense, the only valid path values are 1, 3, 5, and 7.

Pathway number to use for the connections

A pin number or an instrument terminal ID
