/SWITCH=switch-character Specifies a character sequence that you can use to switch the line to PPP mode. To activate PPP mode, type Ctrl/switch- character. You can select any ASCII character from @ though Z, except C, M, Q, S, and Y. The default switch character is @. Similar to the CONNECT command, this qualifier switches a line into PPP mode. If the packet negotiations fail, PPPD exits and the line is left in terminal mode. If line is set to /MODEM and /NOHANGUP, this can result in extraneous data, the ASCII representation of Internet Protocol (IP) packets, being transmitted across the open line.
