Do you have the file .exrc in your home directory? Thay has controls over what vi does and how it behaves. There is also the following snippet from the man page for vi:-
Quote:
window (wi=) Sets the number of lines displayed in one window of text. The
default depends on the baud rate at which you are operating: 600 baud or less, 8
lines; 1200 baud, 16 lines; higher speeds, full screen minus 1 line.
It is also possible that you have a short terminal defined somehow, perhaps.
Another snippet is the setting for z:-
Quote:
zNumber Makes the window the specified number of lines long.
.... again probably in ~/.exrc
I'm not sure if this helps, but maybe......
Anyone else?

NAME
dial(), undial() - establish an outgoing terminal line connection
SYNOPSIS
DESCRIPTION
The function returns a file descriptor for a terminal line open for read/write. The argument to is a structure (defined in the header
file).
When finished with the terminal line, the calling program must invoke to release the semaphore that has been set during the allocation of
the terminal device.
The definition of in the header file is:
elements are as follows:
speed Intended only for use with an outgoing dialed call, in which case its value should be either 300 or 1200 to identify the
113A modem, or the high- or low-speed setting on the 212A modem. Note that the 113A modem or the low-speed setting of the
212A modem transmits at any rate between 0 and 300 bits per second. However, the high-speed setting of the 212A modem
transmits and receives at 1200 bits per second only.
baud Desired transmission baud rate. For example, one might set baud to 110 and speed to 300 (or 1200). However, if speed is
set to 1200, baud must be set to high(1200).
line If the desired terminal line is a direct line, a string pointer to its device name should be placed in the line element in
the structure. Legal values for such terminal device names are kept in the file. In this case, the value of the baud
element need not be specified as it will be determined from the file.
telno A pointer to a character string representing the telephone number to be dialed. Such numbers can consist only of symbols
described below. The termination symbol is supplied by the function, and should not be included in the telno string
passed to in the structure.
Permissible Codes
Dial

Dial
4-second delay for second dial tone
End of number
Wait for secondary dial tone
Flash off-hook for 1 second
modem Specifies modem control for direct lines. Set to non-zero if modem control is required.
attr Pointer to a structure, as defined in the header file. A NULL value for this pointer element can be passed to the func-
tion, but if such a structure is included, the elements specified in it are set for the outgoing terminal line before the
connection is established. This is often important for certain attributes such as parity and baud rate.
device Holds the device name that establishes the connection.
dev_len Length of the device name that is copied into the array device.
RETURN VALUE
On failure, a negative value indicating the reason for the failure is returned. Mnemonics for these negative indices as listed here are
defined in the header file.
WARNINGS
Including the header file automatically includes the header file.
The above routine uses which causes unexpected increases in the size of programs that otherwise do not use standard I/O.
The function will modify the values of some of the fields of the structure so if is reinvoked, it will reinitialize the values of the
structure.
