- Ok. I'm really frustrated now.
-
- I've been mucking with our uucp configuration recently (got some new faster
- modems) and have seem to found an odd limit/bug in SunOS 4.1.1 uucp
- (basically BNU/HDB SVR3 uucp).
-
- As an example, I had several sites configured as such:
-
- Systems excerpt:
- foosite Any ACU tb19200 Out5551212 ogin:--ogin: xxxxx ssword: xxxxx
- Devices excerpt:
- ACU ttyz05 - tb19200 tbplus
- ACU ttyz05 - tb9600 tbplus
- Dialers excerpt:
- tbplus =W-, "" \dA\pT\r\c OK\r \pATDT\T\r\c CONNECT STTY=crtscts
-
- The modems were configured/locked to talk at 19200, and dialing out using
- tip(1) worked fine (as well as dialing in). However, I could not get cu(1)
- to dial out, and, when I watched the uucico debug output, it appeared to be a
- speed problem.
-
- So, I dropped the speed on the modems to 9600 and changed the line from the
- Systems file to be:
- foosite Any ACU tb9600 Out5551212 ogin:--ogin: xxxxx ssword: xxxxx
-
- Now everything works fine (except slower). The SunOS 4.1.1 "System and
- Network Administration Guide", section 3 "Network Communications
- Administration", chapter 21 "Administering the UUCP System", says that direct
- links may achieve "[t]ransfer rates of up to 19200 [bps]." There is no such
- restriction listed just below in the paragraph describing Telephone line
- connections using ACUs, nor anywhere else that I have looked.
-
- Ok, so here comes my question: It this version of the UUCP software that
- brain-dead that I can't run ACU devices faster than 9600 bps? If so, is
- there a system patch somewhere that I can apply to alter this fact? If not,
- this must be a "bug."
-
- Other potentially relevant systems information: SunOs 4.1.1 on Sparc2.
- Modems connected using a Sun "Serial Parallel Controller" in an SBus slot
- (adds 8 serial ports and 1 parallel port). Note that the documentation for
- this product explicitly states that I may run devices at speeds upto 38400.
- Modems in question: Telebit T3000, Telebit TrailBlazer Plus, MultiTech
- MultiModem V.32.
-
- TIA for any help,
- Eric
