NOTES: 1) An RXMT station operating in EDM mode will pass both EDM and SDM
data traffic, as well as voice messages.
2) For RXMT of RS-232 data, both RXMT radios must be set to the data
rate used for RS-232 data transfer. Transfer of data by RS-232 mode
through an RXMT station requires a longer time than FH only RXMT or
point-to-point RS-232 traffic.
3) Mixed mode RXMT (SC to FH, FH to SC) of data traffic can be passed in
SDM mode only not in EDM mode.
