This is a standard terminal set of Escape sequences which perform many sophisticated functions (open a series of blank lines, scroll a portion of the screen, display misc types of highlighting, etc.). ANSI terminal emulation is a SUPERSET of VT52. That is, it includes as a portion of the standard the capability to emulate a VT52. The VT52 was one of the early terminals which could do cursor addressing. Almost all of the sequences to open new lines, etc. are a single control character. Thus, the number of useful things that VT52 can do are quite limited (about15-20). The VT52 is MUCH easier to emulate than a VT100 since the pgm only has to scan for the single control character. The ANSI escape sequences sometimes can be dozens of characters long! If you have line noise, it can cause problems in that a sequence is misinterpreted. Saying all of this, let me mention 3 alternatives. Kermit 3.80 has a VT100 emulation mode. I STILL have not gotten a version to work on my GS; when I do, perhaps I will remember to let you know how good it is at 2400 baud. DCOM is a product being sold (at one time the author read this group) which is supposed to be quite a Good VT100 emulator. And finally, ProTerm 1.9 something is available and has a reportedly pretty good VT100 emulator. -- Larry W.
