Note that during Linktest installation only desired supported communication APIs are installed by setting the corresponding environment variable to `1` to install or `0` to not install. As such a given Linktest executable may not support all the listed communication APIs. By default all communication APIs are supported after installation, however this rarely builds successfully as most platforms do not support all communication APIs due to a lack of relevant hardware.

# Communication Time
|
|
|
The communication time in Linktest is the time it takes from when a message is ready to be sent till it arrives at the recipient and a receipt is returned. Linktest tests two-way communication times, which is the time it takes between the message being ready to be sent till that message is returned and a receipt is sent. This is referred to as the two-way communication time. As opposed to the one-way communication time which is the time from the message-being ready to be sent till a receipt is received that the message has been successfully delivered. If bidirectional testing is used, both communication partners send their identical messages at the same time and timing ends when a partner receives a receipt.
