11-18-93 Dialtone / BUSY Problems
Some places (more often in Europe than in the US) or on some in-house
phone systems, the modem may not recognise Dialtone or BUSY, in rare cases
both. In this case use X1, X2 or X3 in the dial prefix (ATX1DT) or the
init string. X1 will see neither Dialtone nor BUSY, X2 will see Dialtone
only, and X3 will see the BUSY only. If the software/fax doesn't have a
place for init, change call-progress to NONE.
There is also X2 if you have trouble with false BUSY, but can
recognise dialtone (can happen w/voice answer fax machines).
Sometimes putting a '@' at the end of the dial string helps (after the
phone number, as that waits for 5 seconds of silence after the other end
picks up the phone. (will wait for silence after a voice answer).
The modem uses only 2 wires on the phone line, the center 2 wires. A
phone which uses other wires can still get it's signals through the other
wires, even though the modem cannot see them.
If you have trouble dialing PULSE there is a command to change the
pulse make/break ratio needed in some areas (usually overseas). &P (see
your manual).
