Modem Characteristics
of a modem connect (CONTROL 11) procedure call, the system
ensures that the communication line is disconnected. For ATP6100
subdevices, you can change the SYSGEN default by including the
AUTODCONN attribute in a CMI ALTER SU command.
Certain modems and terminals require one or two special
turnaround characters for switching between send and receive
modes. The HDTURN1 and HDTURN2 SYSGEN modifiers specify these
characters. For ATP6100 subdevices, you can change the SYSGEN
default by including the HDXTURNCHAR attribute in a CMI ALTER SU
command.
Only one flow control method (ETX(ENQ)/ACK, TPAUSE, REVTPAUSE,
XON/XOFF, or CTSFLOW) can be selected at one time.
After modem-attached subdevices have been configured, use the
CONTROL procedure call to activate and deactivate the modem.
CONTROL 11 directs the application to wait for the modem
connection. CONTROL 12 disconnects the modem without closing the
file. You can issue these commands only if AUTODCONN is set ON. |
