Use the dlWrite function with the pOptArgs.usProtCommand field set to
DLI_PROT_START_AUTODIAL to send a BSC 2780/3780 Autodial Start command. The buffer
pointed to by the
pBuf parameter contains a string of a variable number of 8-bit bytes
(up to 256) containing the dial string.
An autodial start acknowledge response with the dlRead pOptArgs.usProtCommand field
set to
DLI_PROT_START_AUTODIAL is sent to the client when the BSC 2780/3780 software
receives a message from the modem indicating that the connection has been made. The
buffer pointed to by the
pBuf parameter contains the string of responses from the
modem. The Autodial Start command supports SADL (Synchronous Autodial Lan-
guage), Hayes AT-compatible, and V.25bis (byte synchronous) modems. The modem
type is selected with the modem type option (Section 6.29 on page 182).
An unsuccessful Autodial Start command can return one of the error codes listed in
Ta ble 5 –6 in the
dlRead pOptArgs.iICPStatus field of the autodial start acknowledge (see
Appendix D for error handling):
