CALL(1)

NAME
call - make an AX.25 or NET/ROM connection.

SYNOPSIS
call [-b l|e] [-d] [-m s|e] [-n] [-p port] [-w window] callsign [[via] digipeaters.....]

DESCRIPTION

Call is the general purpose AX.25 and NET/ROM connection program. As is normal in AX.25 it runs entirely in line mode. All CR/LF translation is done transparently. The program provides ASCII, YAPP, and YAPP-C file transfer facilities. Some of the options are only valid in AX.25 mode, the program will quietly ignore them if given in NET/ROM mode.

OPTIONS

-b l|e
    Sets the method of backoff to use with AX.25 connections. The default is taken from the port specification, but can be overridden by this option. Valid values are l for linear backoff, and e for exponential backoff.

-d  Turn on socket level debugging.

-m s|e
    Sets the AX.25 mode to use. The default is taken from the port specification, but can be overridden by this option. Valid values are s for normal (modulus 8) AX.25 operation, or e for extended (modulus 128) AX.25 operation.

-n  Connect to a NET/ROM call or alias instead of an AX.25 call.

-p port
    Select a port to use (the default is 1).

-w window
    Specify a specific AX.25 window for this connection. Only valid in AX.25 mode.

The call program interprets lines beginning with a '~' specially. The following '~' escapes are available.

~?  List escapes

~~  A ~ symbol

~Z  Suspend program

~.  Close connection

~! [command]
    Run a command

~o [filename]
    Open a logfile (default 'logfile.txt')

~c  Close the logfile

~u [filename]
    Upload a file (ASCII upload)

~yu [filename]
    Upload a file (YAPP upload)

~yd [filename]
    Download a file (YAPP download)

The program provides no terminal emulation features. These are left up to the console facilities of the terminal in use. The program is however '8 bit clean'.

BUGS
A certain amount of 7plus support in the program itself would be a great boon.
