8 | * Racal-Vadic 'RV811' MACS system with 831 adaptor. | |
9 | * | |
10 | * A typical 300 baud L-devices entry is | |
11 | * ACU /dev/tty10 /dev/tty11,48,1200 300 vmacs | |
12 | * where tty10 is the communication line (D_Line), | |
13 | * tty11 is the dialer line (D_calldev), | |
14 | * the '4' is the dialer address + modem type (viz. dialer 0, Bell 103), | |
15 | * and the '8' is the communication port | |
16 | * (Note: Based on RVMACS version for 820 dialer. This version | |
17 | * developed by Doug Kingston @ BRL, 13 December 83.) | |
