|tvm IVO for your fast answer. one of the computers is an ibm thinkpad 560z notebook (the one with nt), has a mobile pentium II 233 mhz 512 kb l2 cache processor, 96 mb ram, 4 gb hdd and a pci bus capable of 32-bit transfers. it also has support for two type II pc cards but they're already filled with two pcmcias (us robotics 56k modem and ibm 4x cd-rom drive). it hasn't any pcmcia networking card that i could use. i had never used this notebook any more since the old win95 days but it has some important information that i need just now. i was fearing that this oldie could not support speeds beyond 9600 but bearing your answer in mind i tried with 38400 first, then 57600, and later with 115200 and it worked fine with this last one, no losses at all, so now i can get back the information regarding old clients. once more thank you very much for your help.|
by the way, i'm not using the 56k modem for this, i connected both computers thru their serial ports instead (the other computer is a pcchips p55g v1.0 motherboard with an intel core 2 duo processor, 4 gb ddr2 ram, geforce7050/610i chipset and 32-bit win xp sp3).
