UUCP /etc/uucp/Dialers File

The /etc/uucp/Dialers file contains dialing instructions for commonly used modems. You probably do not need to change or add entries to this file unless you plan to use a nonstandard modem or plan to customize your UUCP environment. Nevertheless, you should understand what is in the file and how it relates to the Systems and Devices file.

The text specifies the initial conversation that must occur on a line before the line can be made available for transferring data. This conversation, known as a chat script, is usually a sequence of ASCII strings that is transmitted and is expected. A chat script is often used to dial a phone number.

As shown in the examples in UUCP /etc/uucp/Devices File, the fifth field in a Devices file entry is an index into the Dialers file or a special dialer type, such as TCP, TLI, or TLIS. The uucico daemon attempts to match the fifth field in the Devices file with the first field of each Dialers file entry. In addition, each odd-numbered Devices field, starting with the seventh position, is used as an index into the Dialers file. If the match succeeds, the Dialers entry is interpreted to perform the dialer conversation.

Each entry in the Dialers file has the following syntax:

dialer   substitutions   expect-send

The following example shows the entry for a U.S. Robotics V.32bis modem.

Example 26-10 Entry in /etc/uucp/Dialers File

usrv32bis-e    =,-,  ""    dA\pT&FE1V1X1Q0S2=255S12=255&A1&H1&M5&B2&W\r\c OK\r 
                           \EATDT\T\r\c CONNECT\s14400/ARQ STTY=crtscts

Entry in the Dialer field. The Dialer field matches the fifth and additional odd-numbered fields in the Devices file.

=,-, ""

Entry in the Substitutions field. The Substitutions field is a translation string. The first of each pair of characters is mapped to the second character in the pair. This mapping is usually used to translate = and - into whatever the dialer requires for “wait for dial tone” and “pause.”

dA\pT&FE1V1X1Q0S2=255S12=255&A1&H1&M5&B2&W\r\c OK\r

Entry in Expect-Send field. The Expect-Send fields are character strings.

\EATDT\T\r\c CONNECT\s14400/ARQ STTY=crtscts

More of the Expect-Send field.

The following example shows sample entries in the Dialers file, as distributed when you install UUCP as part of the Solaris installation program.

The following table lists escape characters that are commonly used in the send strings in the Dialers file.

Table 26-3 Backslash Characters for /etc/uucp/Dialers

Sends or expects a backspace character.
No newline or carriage return.
Delays for approximately 2 seconds.
Phone number or token without Dialcodes translation.
Disables echo checking.
Enables echo checking for slow devices.
Inserts a Break character.
Sends newline.
Sends octal number. Additional escape characters that can be used are listed in the section UUCP /etc/uucp/Systems File.
Sends or expects a NULL character (ASCII NUL).
Pauses for approximately 12–14 seconds.
Sends or expects a space character.
Phone number or token with Dialcodes translation.

Here is a penril entry in the Dialers file:

penril =W-P "" \d > Q\c : \d- > s\p9\c )-W\p\r\ds\p9\c-) y\c : \E\TP > 9\c OK 

First, the substitution mechanism for the phone number argument is established so that any = is replaced with a W (wait for dial tone) and any - with a P (pause).

The handshake that is given by the remainder of the line works as listed:

Enabling Hardware Flow Control in the /etc/uucp/Dialers File

You can also use the pseudo-send STTY=value string to set modem characteristics. For instance, STTY=crtscts enables outbound hardware flow control. STTY=crtsxoff enables inbound hardware flow control. STTY=crtscts,crtsxoff enables both outbound and inbound hardware flow control.

STTY accepts all the stty modes. See the stty(1) and termio(7I) man pages.

The following example would enable hardware flow control in a Dialers entry:

dsi =,–, "" \dA\pTE1V1X5Q0S2=255S12=255*E1*F3*M1*S1\r\c OK\r \EATDT\T\r\c 

This pseudo-send string can also be used in entries in the Systems file.

Setting Parity in the /etc/uucp/Dialers File

In some situations, you have to reset the parity because the system that you are calling checks port parity and drops the line if it is wrong. The expect-send couplet P_ZERO sets parity to zero:

foo =,-, "" P_ZERO "" \dA\pTE1V1X1Q0S2=255S12=255\r\c OK\r\EATDT\T\r\c CONNECT 

The following are parity couplets that can follow the expect-send couplet:


Sets the parity to even, which is the default

"" P_ODD

Sets the parity to odd

"" P_ONE

Sets the parity to one

This pseudo-send string can also be used in entries in the Systems file.
