Looking for UNIX telecom program

[bailey at mfci.UUCP]

I am looking for a UNIX based serial comm program that will
allow controlling a remotely connected system console with
commands issued from a text file.

I need something that will allow me to interact with the
connected console through some scripting language with
decision making capability.  

For instance, some basic commands might be:

TYPE "login"            /* send the chars "login" to remote dev */
WAIT 10                 /* do nothing for 10 seconds */
PROMPT "password:"      /* wait for prompt "password:" */
TYPE "foo"              /* when found, send chars "foo" */

Other useful commands would be:

<label>                       /* label for branching to from above */
WATCHFOR "<string>" <label>   /* if <string> is found jump to <label> */
PANIC 20 <label>              /* if nothing happens in 20 seconds, 
                                 jump <label */

Programs like ZCOMM, PROCOM, etc for the PC and Red Ryder
for the MAC have this capability.

Anybody have any suggestions?
