'' 'ATE1'
Turns out this is neither needed to debug the chat script nor needed in
the final script:
TIMEOUT 30
'' AT+CFUN=1\r\d\c # wait until the modem echoes '+PACSP0'
'+PACSP0' # chat(8) says '/d' '/c' not valid for 'expect'
Here is a better way to work around this:
TIMEOUT 5
ABORT 'NO CARRIER' ABORT ERROR ABORT 'NO DIALTONE' ABORT BUSY ABORT 'NO
ANSWER'
TIMEOUT 30
'' AT+CFUN=1 T+CFUN=1 # just "eat up" all 'expect'
'' OK # ''
'' '+PACSP0' # ''
'AT+CGDCONT=1,"IP","isp.cingular"'
OK\r\n 'ATDT*99***1#' # straight from chat(8)
\r\n \c # ''
CONNECT \c # ''
