CONNECTION Type: Immediate Format: AT [cmds] %Q1 [cmds] Description: Displays information on the connection Connection Display V.32/V.32bis EQM: (same as %Q) Receive Level: (same as %L) Transmit Level: (current TX level in dBm) V.FC/V.34 Far Echo Delay: (round trip far end echo delay in ms) Far Echo Level: (signal Strength of far echo in dBm) Pre-Emphasis Filter: (filter in use to normalize the lines frequency response as per V34 DSP specs. and ITU V.34 specs.) V.34 only SNR: (signal to Noise ratio measured during the line probe, in dB) Normalized Bandwidth: (The -3dB roll off points after the pre-emphasis filter is applied. This is not the same as the usable audio band-width since the signal has been heavily processed prior to this measurement. This range determines the maximum symbol rate the line will support.) Baud rate: (symbols per second on the connection) Transmit Carrier: If the symbol rate is below 3429 there are two available carrier frequencies. (A high carrier and a low carrier.) The actual frequency of the carriers varies with the symbol rate. "high" or "low" are the only items displayed. Received Carrier: same as above on received carrier RTS/CTS Type: Configuration Format: AT [cmds] &Rn [cmds] Description: Selects RTS/CTS options Command Function &R0 In Sync mode CTS follows RTS In Async mode CTS forced high &R1 In Sync mode CTS forced high In Async mode RTS/CTS forced high SC-REGISTERS Type: Register Format: AT [cmds] SCn=x [cmds] Description: Each register "pair" holds the value for each setting. To set a value, divide the setting by 256. The integer goes in the second register, while the remained goes in the first. (A setting of 516 would convert to 2 Remainder 4, and could be set by sending ATSC0=4SC1=2 to the modem.) Settings are in 1/100ths of a second. Setting SC0=22 & SC4=22 allows FAST BUSY to also be detected as BUSY.
