The old way *should* still work, and it does still work with real modems on
real serial ports. The reason we need TAPI is not so much because it's
wonderful, but because it is the ONLY way to use the decidedly UN-real modems
that come preinstalled in most PCs these days (see the Kermit FAQ for rants
about Winmodems and the like).
Still, in either case, you'll normally need to do a couple things prior to
CONNECTing to a bare modem (rather than DIALing the modem):
set carrier-watch off
set flow none
That's because (a) the modem is not (or at least should not be) presenting
the carrier signal when it doesn't have a connection and (b) if the flow
control is set RTS/CTS (as it normally is for modern modems), the modem might
not be presenting its CTS signal yet.

: some things over the phone when they have troubles.)
:
K95 does give you the appropriate hints if you try to CONNECT to a serial
port that is not presenting the normal modem signals. From K95 1.1.17:
[C:\k95\] K-95> set port 1
[C:\k95\] K-95> connect
No carrier detected on com1.
Hint: Use the DIAL command, or else SET CARRIER OFF.
If you want to make a network connection, use SET HOST or TELNET.
[C:\k95\] K-95>set carrier off
[C:\k95\] K-95>connect

OK
