Description
Radio link protocol (RLP) parameters used when non-transparent data calls are originated may be altered with set
command. Available command subparameters depend on the RLP versions implemented by the device (e.g. <ver>
may not be available if device supports only versions 0 and 1).
NOTE 1: If radio link protocol is not used, but some other error correcting protocol (for transparent data calls),
V.250 [14] Error Control Selection test command +ES=? may be used to indicate the presence of the
protocol.
Read command returns current settings for each supported RLP version <verx>. Only RLP parameters applicable to
the corresponding <verx> are returned.
