You're missing something. The documentation doesn't
contain all the information. Later releases of the
system contain the following comments in the
Dialers file:
# Hayes Smartmodem -- modem should be set with the configuration
# switches as follows:
#
# S1 - UP S2 - UP S3 - DOWN S4 - UP
# S5 - UP S6 - DOWN S7 - ? S8 - DOWN
#
#hayes =,-, "" \dAT\r\c OK\r ATDT\p\c \T\r\c CONNECT
# Hayes Smartmodem -- new BNU modem control capabilities
# If you do not want to strap CD on, use these switch settings:
#
# S1 - UP S2 - UP S3 - DOWN S4 - UP
# S5 - UP S6 - UP S7 - ? S8 - DOWN
#
# and this dialer entry (comment out the earlier one):
#
hayes =,-, "" \M\pAT\r\p\c "" ATDT\p\c "" \T\r\m\c CONNECT
#
# Furthermore, you must add a ",M" subfield to the line field (field
# 2) of the associated Devices file entries, as shown here:
#
# ACU culd0,M - 1200 hayes \T
#
# The ",M" subfield will cause the device to be opened with O_NDELAY set
# (so the open doesn't hang waiting for carrier). After the open,
# O_NDELAY is cleared. Then in the dialer script, "\M" sets CLOCAL and
# "\m" clears it. Typically, CLOCAL is set for the duration of the
# dialer chat, then cleared (so uucico and cu will detect dropped lines)
# once you're connected to the remote system.
