Enumeration Type Documentation

enum KISS_CHARS

KISS protocol special characters. Enumeration values: KISS_FEND  Frame End. KISS_FESC  Frame Escape. KISS_TFEND  Transposed Frame End. KISS_TFESC  Transpoded Frame Escape.

enum KISS_CMD

KISS protocol commands. Enumeration values: KISS_CMD_DATA  The rest of the frame is data to be sent on the HDLC channel. KISS_CMD_TXDELAY  The next byte is the transmitter keyup delay in 10 ms units. KISS_CMD_PPERSIST  The next byte is the persistence parameter, p, scaled to the range 0 - 255. KISS_CMD_SLOTTIME  The next byte is the slot interval in 10 ms units. KISS_CMD_TXTAIL  The next byte is the time to hold up the TX after the FCS has been sent, in 10 ms units. KISS_CMD_FULLDUP  The next byte is 0 for half duplex, nonzero for full duplex. KISS_CMD_SETHW  Specific for each TNC.

enum LPMODEM_CTL

lpmodem ioctl commands. Enumeration values: LPMODEM_GET_DCD  Get the DCD state. LPMODEM_GET_PTT  Get the ptt state. LPMODEM_SET_TXDELAY  Set the transmitter keyup delay in 10 ms units. LPMODEM_SET_PPERSIST  Set the p-persistence scaled to the range 0-255. LPMODEM_SET_SLOTTIME  Set the slot interval in 10 ms units. LPMODEM_SET_TXTAIL  Set the time to hold up the TX after the FCS has been sent, in 10 ms units. LPMODEM_SET_FULLDUP  Set to zero for half duplex, nonzero for full duplex. LPMODEM_GET_STAT  Get lpmodem statistics. LPMODEM_GET_PARAMS  Set KISS lpmodem parameters. LPMODEM_SET_PARAMS  Get KISS lpmodem parameters. LPMODEM_GET_MSR  Get MSR register. LPMODEM_GET_REG  Get ST7538 Register register. LPMODEM_SET_REG  Set ST7538 Register register.
