Hi,
I have been having a problem with trying to run programs like vi
on other systems from my Apollo workstation. Basically, what I recently
tried doing was:
1) vt100 <-enter the vt100 emulator.
2) crp -on e4c0 -me <-move over to a node that has telnet running
3) telnet bozo <-connect to another node (in this case a Sun)
4) login to bozo
5) tset vt100 <-set terminal type to vt100
6) set term=vt100 <- ""
7) vi test.c
Now, the screen addressing seems to work ok and the file loads up ok, but
I am still in a mode where I have to enter a return after each command I
want to execute (i.e. the j,k,l,h, etc keys...) There must be some way of
getting the vt100 emulator to transmit a character at a time, but I am at
a loss as to how to do this! It isn't anything related to the system I log
into, but rather the emulator (or telnet), buffering by line. Has anyone
else had this problem and solved it? Also, the Apollo appears to be sending
a cr/lf pair (which screws up other screen programs...)

The problem is crp. It only supports a line at a time mode. Complain to apollo, and it might get fixed some year. One other possibility is to use the TCP/IP package and telnet or rlogin. Both of those programs are character at a time interfaces. -joey

As with a lot of Apollo stuff, the problem isn't with missing functionality, it is with missing documentation (not a whole lot better, I agree). Programs running in a CRP'ed process can configuring the pad on the controlling node to be in raw mode, can program the function keys, etc. One can look at the source for EMT to see how this is done. For example, I hacked an early version of C-Kermit so it runs properly (i.e., gives the standard C-Kermit (and TOPS-20) character-at-a-time interface) from an sio login, from a pad, from a CRP'ed process and from under the vt100 emulator. Unfortunately, I can't seem to get it to work when CRP'ed from an sio login nor when CRP'ed from a VT100 emulator. In case any one is interested, I have about 370 lines and 14K of C code I can send you, showing how its done. Apologies: I lost the thread on what the original article mentioned, so this may not answer any of the original questions. ---------------------------------------------------------------------------- Prof. Neal Holtz (Until Internet registration completed:) Dept. of Civil Engineering CDNnet: Holtz@cascade.carleton.cdn Carleton University CSNET: Holtz%cascade.carleton.cdn@ubc.csnet Ottawa, Ontario ARPA?: Holtz%cascade.carleton.cdn%ubc.csnet@relay.cs.net Canada K1S 5B6 (613) 564-2677, -4315 (msgs)
