See võib küll töötada "teatud" seadmete ja "teatud" softi või OS-i seadetega... Võibolla tüüneritega on kama, aga teiste sedmetega on jama
"Here's another null-modem connection that I've seen floating around the net. Some folks say that it's the cable that's shipped with LapLink 4 Pro.
Personally, I don't think that a null-modem cable built to the above pinout will work quite as well, but a lot of folks appear to have success with it. In general, it will work with some software packages, such as those that only use RTS/CTS hardware flow control. However, some packages that rely on the proper assertion of the CD signal will not work with this cable."
a) Väidetavalt korrektne "Full handshaking NULL modem" kaabel.

b) Või hoopis "Null modem with partial handshaking"

Isiklikud kogemused ilma pin1-ta "Laplink" kaabliga - COM1 pordiga läpakaga töötas. Teisel läpakal, mille oli Windows XP ja puudus COM port, kasutasin USB-COM adapterit - ei toiminud, pärast ümberühendamist korrektseks NULL-modem kaabliks toimis. Millegiga tuleb "Carrier Detect" (DB9 pin 1) ühendada, sest XP HyperTerminal viskab muidu pidevalt "Toru hargile".
