Command (C4):
FREQUENCY FACTOR FOR TONE #1
( 15 - 0 )
Status (S4):
FREQUENCY FACTOR FOR TONE #1
( 15 - 0 )
After new tone definition has been made in the table, any of the new defined tones can be generated in the usual way.
FSK Modem
This mode allows support of the CID function,
a
-5, as well as general purpose FSK receive and transmit mode with
optional HDLC framing and optional RS-232 encapsulation.

- Defines the master gain of Transmission. The actual gain will be from -24 dB (gain code 1111) to +6
dB (gain code 0000). The gain code equals: 0 =< (GainX + MASTER GAIN)< =15
NO CS

Command C2 - C5 are setup commands. For Receive Only mode value of the C2 - C5 commands are not important.
Host can send, for example, Idle commands.
The order of Receive Command (C7) and Transmit Command (C6) depends on the FSK Configuration. For “Transmit
before Receive” mode C7 command will precede C6.
