The only example of VMS speaking Hayes I know of is when using SET HOST/DTE with something like a /MODEM=xxx qualifier and the corresponding user-provided DTE_xxx.EXE in SYS$LIBRARY. See SYS$EXAMPLES:DTE* for more information. :) OpenVMS VAX V7.2 has a couple DTE_*.MAR sample files, while OpenVMS Alpha V8.3 has a nice DTE_AT.C dialer. Maybe other versions have others and if I'm not wrong there should be something quite useful in the DECUS libraries too... HTH, :) G.
