S50 Error Correction Auto Detection Timeout
Default: 50 (5 sec) Min:1 Max: 255
This register defines how long, in units of 100ms, a modem will attempt auto-detection of an error control
protocol (in answer mode) before giving up and establishing a normal (non error-controlled) connection. During
the auto-detection phase the modem will respond to an ODP sequence, HDLC flags, the configured fallback
character, or MNP2 flags. If none of these are detected within the specified time, a normal link/connection is
established.
S51 Error Correction Fallback Character
Default: 13 (‘\r’) Min: 0 Max: 127
This register defines the ASCII character that, if detected repeatedly (while in answer mode) is attempting auto-
detection of an error control protocol, will cause the EC negotiation attempt to be abandoned and a normal (non
error-controlled, asynchronous) link to be established. The character must be received three times
consecutively. The default character is the Carriage Return (CR). The value of this register is in decimal.
