Prosody data communications Protocols: V.29 rx

V.29 is an ITU-T standard modem.

This protocol implements the receiver for V.29. Since it is only a receiver, it only uses the input half of a channel. Typically the output half is configured for V.29 tx.

API function behaviour

This should be read in conjunction with the generic data communications documentation.

smdc_channel_config()

You must use #include "smdc_v29.h" to get the appropriate declarations.

The protocol value is kSMDCProtocolV29rx.

The config_data pointer must point to one of these structs:

	typedef struct smdc_v29_config_parms {
		tSM_INT speed;
	} SMDC_V29_CONFIG_PARMS;

'speed' is the data rate in bits per second. This must be one of the standard speeds: 4800, 7200, or 9600.

This protocol can use these encodings: SYNC, ASYNC, HDLC.

The firmware modules v29rx and inchan must have been downloaded.

smdc_line_control()

[note] not useful - receiver is always connected

smdc_line_status()

smdc_tx_status()

This function is not applicable since it only applies to the output half of a channel.

smdc_tx_control()

This function is not applicable since it only applies to the output half of a channel.

smdc_rx_status()

smdc_rx_control()

smdc_rx_data()

smdc_tx_data()

This function is not applicable since it only applies to the output half of a channel.
