I recently purchased a TELEBIT Trailblazer Plus, and am using it on my AT Clone until I can get my Unix system. After getting the modem, I noticed that my communications package, GT-COMM (Ver. 12.10), only supported up to 9600 baud, and was told my someone that DOS could only handle up to 9600 Baud.. I hate having a modem that has to wait for my system when I logon at 19.2k!! So, does anyone have any ideas on how to get around the 'problem'? Is there a software package out that supports 19.2k on an AT? For that matter, will the AT even support 19.2k? Any help is highly appreciated!! Please reply via E-mail, since I usually don't have time to read all the messages in comp.sys.ibm.pc...

Mark of the Unicorn sells a VT100 emulator that supports 19200 baud on PC/XT/AT. I expect a fair number of other terminal emulators are this smart. I've even seen, a couple of years ago, an example of file transfer at 57600 baud from BASIC, involving PEEK and POKE statements. (Alas, Microsoft BASIC has the best built-in RS-232 support of any high-level language on the PC). Clayton E. Cramer

Realia VT-Termulator does pretty well at 19.2 KB even on a PC. It's mostly a matter of programming. Mike Berger Department of Statistics Science, Technology, and Society University of Illinois berger@clio.las.uiuc.edu {ihnp4 | convex | pur-ee}!uiucuxc!clio!berger

Try Pro-YAM from Omen Technology. Far superior to anything on the
market, except in its user interface. The author is Chuck Forsberg,

The maximum speed without dropping characters depends on many factors. Terminal emulators differ in their speed, especially when scrolling or decoding and executing escape sequences. Pro-YAM and its shareware cousin ZCOMM are among the fastest and most accurate in VT10x emulation. The actual max speed also depends on the operating system, device drivers, and TSR programs. Professional-YAM on a PC XT can download files or display screenfulls at 19200 bps without losing any characters when run under DOS 2.1. Under DOS 3.x, a few characters are lost, about one in a hundred thousand. When writing to certain disk systems, characters can be lost at 2400 bps! Emulation modes of trick EGA/VGA cards are almost as bad. Replacing the 8250 or 16450 UART ships with the new National NS16550AN allows Pro-YAM to activate a 16 deep FIFO register. This increases the allowable interrupt latency by almost an order of magnitude. It is possible to send data to Pro-YAM at 115kb using ZMODEM, and get a throughput of 70000-90000 bps; with an ordinary chip, the interrupt latency caused by extended memory ramdisks causes data loss above 9600 bps.

The author is Chuck Forsberg, >reachable at reed!omen!caf. I agree on the kudos for Pro-YAM, but for others contemplating purchase of Pro-YAM, don't let the user interface comments scare you off. No, Pro-YAM isn't PROCOMM or Xtalk. It is not menu driven, and it doesn't have pull-down/pop-up menus. It *is* fully programmable using a C-like language that allows you to do just about anything you want in regards to automated callings and session handling. I have built a 48-entry calling menu with complete login scripts for each of the entries. The scripts are callable via unique names, and can be set up to handle terminal characteristics, logfile names, screen colors, password encryption, and so on. If you can program in C, Pascal, or programmable shells, you can handle Pro-YAM's script language. I apologize for the length of this posting, but I have seen several magazine articles and USENET postings regarding YAM's user interface (or lack thereof) and wanted to do a little record straightening. The program definitely has a serious case of 'Make what you want of it.' Five different YAM users will most likely have five different custom interfaces, and therein lies the beauty. -- Steven C.
