Baud rate problems
I am having a problem with a computer that seems to be stuck on one baud
rate. Whenever I use a program to dial out on the modem. It always connects at 33600. I can manually dial out using AT commands and it will work, but it is almost as though there is a setting some where in Windows XP that is causing the modem to lock in on 33600. I have pasted the log from a session: 8-09-2006 15:57:49.291 - File: C:\WINDOWS\system32\tapisrv.dll, Version 5.1.2600 08-09-2006 15:57:49.291 - File: C:\WINDOWS\system32\unimdm.tsp, Version 5.1.2600 08-09-2006 15:57:49.291 - File: C:\WINDOWS\system32\unimdmat.dll, Version 5.1.2600 08-09-2006 15:57:49.291 - File: C:\WINDOWS\system32\uniplat.dll, Version 5.1.2600 08-09-2006 15:57:49.301 - File: C:\WINDOWS\system32\drivers\modem.sys, Version 5.1.2600 08-09-2006 15:57:49.301 - File: C:\WINDOWS\system32\modemui.dll, Version 5.1.2600 08-09-2006 15:57:49.301 - File: C:\WINDOWS\system32\mdminst.dll, Version 5.1.2600 08-09-2006 15:57:49.301 - Modem type: U.S. Robotics V.92 Fax Win Int 08-09-2006 15:57:49.301 - Modem inf path: oem10.inf 08-09-2006 15:57:49.301 - Modem inf section: Modem1807_2K 08-09-2006 15:57:49.301 - Matching hardware ID: pci\ven_12b9&dev_1007&subsys_00c212b9&rev_00 08-09-2006 15:57:49.331 - 115200,8,N,1, ctsfl=1, rtsctl=2 08-09-2006 15:57:49.331 - Initializing modem. 08-09-2006 15:57:49.341 - Send: ATcr 08-09-2006 15:57:49.341 - Recv: crlfOKcrlf 08-09-2006 15:57:49.341 - Interpreted response: OK 08-09-2006 15:57:49.351 - Send: AT&F1&A0&C1&D2E0Q0V1S0=0+pig=0cr 08-09-2006 15:57:49.361 - Recv: crlfOKcrlf 08-09-2006 15:57:49.361 - Interpreted response: OK 08-09-2006 15:57:49.371 - Send: AT+ILRR=1;+MR=1;+ER=1;+DR=1cr 08-09-2006 15:57:49.371 - Recv: crlfOKcrlf 08-09-2006 15:57:49.371 - Interpreted response: OK 08-09-2006 15:57:49.381 - Send: ATS7=60S19=0L0M1+ES=3,0,2;+DS=3,0;+IFC=2,2;B0X4cr 08-09-2006 15:57:49.391 - Recv: crlfOKcrlf 08-09-2006 15:57:49.391 - Interpreted response: OK 08-09-2006 15:57:49.391 - 1200,7,O,1, ctsfl=1, rtsctl=2 08-09-2006 15:57:49.391 - Initializing modem. 08-09-2006 15:57:49.401 - Send: ATcr 08-09-2006 15:57:49.411 - Recv: crlfOKcrlf 08-09-2006 15:57:49.411 - Interpreted response: OK 08-09-2006 15:57:49.421 - Send: AT&F1&A0&C1&D2E0Q0V1S0=0+pig=0cr 08-09-2006 15:57:49.421 - Recv: crlfOKcrlf 08-09-2006 15:57:49.421 - Interpreted response: OK 08-09-2006 15:57:49.431 - Send: AT+ILRR=1;+MR=1;+ER=1;+DR=1cr 08-09-2006 15:57:49.441 - Recv: crlfOKcrlf 08-09-2006 15:57:49.441 - Interpreted response: OK 08-09-2006 15:57:49.451 - Send: ATS7=60S19=0L0M1+ES=3,0,2;+DS=3,0;+IFC=2,2;B0X4cr 08-09-2006 15:57:49.451 - Recv: crlfOKcrlf 08-09-2006 15:57:49.451 - Interpreted response: OK 08-09-2006 15:57:49.461 - Dialing. 08-09-2006 15:57:49.471 - Send: ATDT#####cr 08-09-2006 15:58:07.278 - Recv: crlf+MCR: V34crlf 08-09-2006 15:58:07.278 - Interpreted response: Informative 08-09-2006 15:58:07.278 - Recv: crlf+MRR: 33600crlf 08-09-2006 15:58:07.278 - Interpreted response: Informative 08-09-2006 15:58:07.278 - Recv: crlf+ER: LAPMcrlf 08-09-2006 15:58:07.278 - Interpreted response: Informative 08-09-2006 15:58:07.278 - Recv: crlf+DR: V42Bcrlf 08-09-2006 15:58:07.278 - Interpreted response: Informative 08-09-2006 15:58:07.278 - Recv: crlf+ILRR: 1200crlf 08-09-2006 15:58:07.278 - Interpreted response: Informative 08-09-2006 15:58:07.278 - Recv: crlfCONNECT 33600crlf 08-09-2006 15:58:07.278 - Interpreted response: Connect 08-09-2006 15:58:07.278 - Connection established at 33600bps. 08-09-2006 15:58:07.278 - Error-control on. 08-09-2006 15:58:07.278 - Data compression on. 08-09-2006 15:58:16.301 - Hanging up the modem. 08-09-2006 15:58:16.301 - Hardware hangup by lowering DTR. 08-09-2006 15:58:16.361 - Detected CD dropped from lowering DTR 08-09-2006 15:58:17.363 - Timed out waiting for response from modem 08-09-2006 15:58:17.373 - Send: ATHcr 08-09-2006 15:58:17.533 - Recv: crlfNO CARRIERcrlf 08-09-2006 15:58:17.533 - Interpreted response: No Carrier 08-09-2006 15:58:17.543 - Send: ATHcr 08-09-2006 15:58:17.553 - Recv: crlfOKcrlf 08-09-2006 15:58:17.553 - Interpreted response: OK 08-09-2006 15:58:17.553 - Session Statistics: 08-09-2006 15:58:17.553 - Reads : 0 bytes 08-09-2006 15:58:17.553 - Writes: 0 bytes |

Baud rate problems
A few things to remember about modems.
1. The connection MODEM to MODEM is the one that BOTH support. 2. 115000 is the internal speed or serial port connection between the PC and the MODEM (NOT modem connection speed) 3. "56k connections" (or anything above 33.6 actually) require a digital phone line on the HOST modem. Given the above any "peer to peer" connection will at best only connect at 33.6k Steve McPheters wrote: I am having a problem with a computer that seems to be stuck on one baud rate.
