5.5MODEM-DRIVER
If you want the terminal defined to be able to work with a modem (using telephone lines
to transmit data), enter the name of the modem driver program at the end of your
TRMDEF line. If you have not specified the EDITOR option, remember to include an
extra comma as a placeholder. Some examples:
TRMDEF TERM1,AM355=1,ALPHA,100,100,100,EDITOR=3,MODEM.DVR
TRMDEF TERM1,AM355=1,ALPHA,100,100,100,,MDM2.DVR
5.6BUILDING YOUR OWN TERMINAL DRIVER
If you want to add a terminal to your Alpha Micro computer system not compatible with a
type of Alpha Micro terminal, you will need to build your own terminal driver for that
device. You can use Alpha Micro terminal driver source files as guides. See the
AMOS
Terminal Programmer’s Guide
for more information.
5.7DEFINING ALTERNATE TERMINAL DRIVERS
You can define alternate terminal drivers to the computer. These alternate terminal
drivers may be selected from AMOS command level by using the SET TERMINAL
DRIVER command. This allows you to switch the driver for your terminal without
changing your initialization file or rebooting your computer. The TDVDEF program
defines alternate terminal drivers to your computer. Enter a TDVDEF command
followed by the names of the terminal drivers you would like to have defined. For
example:
TDVDEF ALPHA,AM60,TV1920
The default extension is .TDV, and the default disk/account is DSK0:[1,6]. If the driver
has already been defined, the new definition is ignored. You can load all of the .TDV
files from DSK0:[1,6] by entering:
TDVDEF *
All TDVDEF commands MUST come before the first SYSTEM command.
5.8ALLOCATING TERMINAL CONTROL BLOCKS
You can use a special form of TRMDEF to allocate a pool of Terminal Control Blocks
(TCBs) or Terminal Definition Units to be used by jobs "spawned" by VTSER and other
similar networking processes. This should be the last TRMDEF statement in your
initialization file. The special command syntax is:
TRMDEF #tcb-number, In-width,In-buffer, Out-buffer
{{,EDITOR}{=Editor-buffer}}{,Modem-driver}
