- Snowcrest Terminal Emulator
-
- The Snowcrest Terminal Emulator program allows the IBM Personal Computer
- series to act as an asynchronous terminal at speeds up to 19,200 baud. The
- emulator program will operate through either the COM1 or COM2 asynchronous
- ports of the computer. Communication can use any parity scheme (8 bit, even
- parity, odd parity, forced mark or forced space). Information received from
- the remote computer can be saved on the printer or on the disk (or both).
- The user may even pass control to DOS, run other programs and return to the
- terminal program without losing information arriving from the remote computer.
-
- Operation -
- The terminal emulator program is first copied from the distribution disk to
- the user's DOS disk using the DOS copy command. The name of the program is
- SNOTERM.EXE.
-
- The program is then executed by typing SNOTERM.
-
- The copyright screen will appear and wait for you to type any key. The
- terminal screen will then appear. This screen is 24 lines high by 80 columns
- wide. The 25th line (status line) details the use of the function keys.
-
- f1- This key ends the terminal emulator and returns to DOS.
- f2- This key sends a BREAK signal to the remote computer. The signal will
- continue to be sent until this key is pressed again.
- f3- This key cycles the baud rates. Each time the key is pressed a new baud
- rate will be selected.
- f4- This key cycles the parity options. "8 bit" will send and receive all
- eight bits of the keys selected (to send the high bits, it would be
- necessary to use the ALT-numeric pad sequence. That is, to send an "a"
- with the high bit on, hold down ALT and type 225 on the numeric keypad.)
- "Even" or "odd" will send and receive even- or odd-parity data. "Mark"
- will send and receive data with the parity bit always on. "Space" will
- send and receive data with the parity bit always off.
- f5- This key turns the Data Terminal Ready line (dtr) on or off on the COM
- port which is selected. Data Terminal Ready is pin 20 of the connector
- and if used with a modem will cause the modem to hang up the telephone
- when turned off.
- f6- This key turns the Request to Send line (rts) on or off on the COM port
- which is selected. Request to Send must be on for most modems to allow
- the computer to transmit data.
- f7- This key will return to DOS while not ending the terminal emulator.
- Other programs may be run as long as they do not use the selected COM
- port. The terminal screen will continue to be updated. Data being sent to
- the disk or the printer will continue to be collected (up to the size of
- the internal buffers - about 25000 bytes), but that data will not be
- written to the printer or disk until the user returns to the terminal
- emulator program by typing "exit" to any DOS prompt.
- f8- This key selects COM1 or COM2 for communications.
- f9- This key turns the printer on or off. The printer will print information
- as it is received.
- f10-This key turns disk collection on or off. All information being received
- will be APPENDED to a disk file named CAPTURE.TXT.
