Additional Comments
Expander triangle

Use the driverNames function to find out which serial drivers can be used with the open driver, read from driver, write to driver, and close driver commands.

Value:

The driverNames function returns a list of drivers, one per line. Each line consists of three items, separated by commas:

1. The name of the driver.

2. The name and location of the TTY device file for the driver.

3. The name and location of the callout device (CU) file for the driver.

Comments:

Usually, you use the callout file name--the third item in the line for the driver you want--with the open driver, read from driver, write to driver, and close driver commands.

If the driverNames function is called on a Mac OS, Unix, or Windows system, it returns empty and the result returns "not supported".
