.SH NAME
em328x \- 328x Printer Emulator
.SH SYNOPSIS 
.I
em328x [hostname]
.SH DESCRIPTION 
The 
.I em328x 
utility is used to emulate the functions
possible on a synchronous printer such as the IBM 3284, 3286, or 3288.
The 
.I hostname 
parameter is used to specify the
control unit interface to be emulated; with the appropriate binary
synchronous driver and corresponding information in the host parameter
file, a 3284/3271, 3286/3271, 3287/3271, or 3288/3271 environment 
can be emulated.
.P
The printer type may be specified in the configuration file
.I (PTYPE=printertype), 
or the default printer type, 4 (3284) may be used.
For more information on printer types
see the reference list at the end of this document.
.P
If a direct connection to the host is available, the connection
will be immediate.
Once the connection is made, the printer will generally behave as
would a 328x printer, with output going to a print spooler or file as
specified in the configuration file.

.SH DIAGNOSTICS
.TP
em3280 <host>: can't open host configuration file <filename>.
The configuration file for this host couldn't be opened.
Either the host name is incorrect, or the modes for the host configuration
file could be wrong.  Processing aborted.
.TP
em3280 <host>: <devname> cannot be opened for communications.
The communications device <devname> for the specified
host could not be opened. Either the mode is set wrong, or some other
process has the device open. Processing aborted.
.TP
em3280 <host>: unrecognized keyword, line <l> in <filename>.
While reading the host configuration file <filename>,
an unrecognized keyword was found on line <l>. Probably a typographical
error. Processing aborted.
.TP
em3280 <host>: invalid parameter for keyword <k> in <filename>.
While reading the host configuration file <filename>,
keyword <k> was found to have an invalid parameter. Probably a typographical
error, but it is also possible that the given parameter was out of
range. Processing aborted.
.TP
em3280 <host>: device <devname> reports modem failure.
The named device reported a transmit timeout error. The usual reason
for this is that the device did not get a transmit clock signal from
the modem. This could be due to improper modem option specification,
improper cable to the modem from the computer system, or to not having
jumpered the MODEM port for external timing. Transmission is
aborted.
.TP
em3280 <host>: <program> not found or not executable.
While attempting to spawn <program> to receive printed data, an error
was encountered. Check the program name and permissions on the file.
Printer data will be discarded until another special function command
for the printer corrects the problem.
