MNP and CIS problems

Hi, This is a general question regarding optimizing my current logon and Whap! sessions. What I've found, despite rumors to the contrary, that I am not able to have Whap! communicate with CIS at 2400 baud, and have my modem communicate with my Amiga at 9600 baud. Since I use MNP 5 (maybe I should be using MNP 4???), from what I've learned on here that increasing the link speed modem->computer should realize some improvement in throughput times. What I've found, however, is that I get a string of xxx~ xx xxx or something like that once I log on to the system. The one thing I've not heard commented on is the correct protocol to use from the serial port and in the software. Does anyone have any suggestions? Should I be using CTS/RTS, XON/XOFF, or NONE as the handshaking method, or is what I'm trying to do not possible??? .. Tim Trompeter…

Tim, Since most of the downloading from CIS is the downloading of archived files which are already compressed, further compression under MNP would just make the files *bigger*, so CIS only uses MNP 4. You should be using CTS/RTS, I think. At least, that is what I am using and it works. Betty

Betty, Thanks, I'll have to reconfigure to use MNP 4, just for default, i guess. .. Tim Trompeter…

Tim, It is very important that you use CTS/RTS handshaking (aka, hardware handshaking) when talking to a "new-fangled" modem at a different speed than the connect speed. Without this enabled, you will have problems. Hope this helps…. – BobR

Bob, Thanks for the information. I checked my preferences, and had XON/XOFF selected as the handshaking protocol (which makes perfect sense only because I have no bloody idea what that means in the first place). I'll take Betty's suggestion and set up the modem to use MNP 4 with CTS/RTS handshaking. I'll set the terminal defaults to 9600 baud, and the modem to "autosense" the baud rate (which I think it's capable of doing). If you have any more great suggestions, just throw 'em my way! ..
