66 Read a byte from the device. Non-blocking read.
69 Read a byte from the device. Blocking read.
72 Rx errors since last query.
75 Write a byte to the device. Always blocks.
78 Write multiple bytes to the device. Collection may be link::Classes/Int8Array:: or link::Classes/String::.
81 A link::Classes/Function:: which will be evaluated if the port gets closed (maybe unexpectedly so, due to hardware failure or accidental disconnection). This allows you to for example to make a backup solution and activate it (like using fake input data for your algorithm, or trying to reopen the device). By default it will post a message to the post window.
