TTYLINK

Command

TTYLINK -- Chat directly to another TCP/IP station

Synopsis

TT[YLINK] <hostname | ipaddress> [port]

Availability

All users except guests.

Description

The TTYLINK commmand allows users of any type (i.e. AX25, console, wire link, TCP/IP) to chat directly to TCP/IP users.

This is similar to TELNET, except that the default port number is 87, which is reserved for keyboard to keyboard chat. Other port numbers may be specified.

This command is deprecated, and may be removed from future versions.

Options

The first argument <hostname | ipaddress> is either the hostname or the IP number of the target system. If the hostname doesn't contain at least one period (.), the domain suffix specified in XROUTER.CFG (default .ampr.org.) is appended.

The optional [port] parameter specifies the desired service on the target host. If not supplied, the default is 87.

Examples

TTY 44.131.91.4       - Chat to user of this IP address
TTY g8pzt             - form if hostname is in domain.sys

Limitations

In order for this command to work, the router must have an IP address and have IP routing defined.

Note

If the target hostname is not known to the router, it will be more efficient to specify the target as an IP address, since this will not require DNS resolution.
